Constructor
Variables
@:value(true)autoBounds:Bool = true
Will automatically adjust the width and height to the members, on add/remove calls
@:value(true)broadcastToFlxUI:Bool = true
If true, will issue FlxUI.event() and FlxUI.request() calls
Methods
calcBounds(?rect:FlxRect):Void
Calculates the bounds of the group and sets width/height
Parameters:
rect | If supplied, populates this with the boundaries of the group |
|---|
Inherited Variables
Defined by FlxTypedSpriteGroup
@:value(false)directAlpha:Bool = false
Whether to attempt to preserve the ratio of alpha values of group members, or set them directly through
the alpha property. Defaults to false (preservation).
4.5.0
.read onlylength:Int
The number of entries in the members array. For performance and safety you should check this
variable instead of members.length unless you really know what you're doing!
Defined by FlxSprite
@:value(1.0)alpha:Float = 1.0
Set alpha to a number between 0 and 1 to change the opacity of the sprite.
See also:
animation:FlxAnimationController
Class that handles adding and playing animations on this sprite.
See also:
@:value(defaultAntialiasing)antialiasing:Bool = defaultAntialiasing
Controls whether the object is smoothed when rotated, affects performance.
@:value(0)read onlybakedRotationAngle:Float = 0
The minimum angle (out of 360°) for which a new baked rotation exists. Example: 90 means there
are 4 baked rotations in the spritesheet. 0 if this sprite does not have any baked rotations.
See also:
clipRect:FlxRect
Clipping rectangle for this sprite.
Changing the rect's properties directly doesn't have any effect,
reassign the property to update it (sprite.clipRect = sprite.clipRect;).
Set to null to discard graphic frame clipping.
@:value(0xffffff)color:FlxColor = 0xffffff
Tints the whole sprite to a color (0xRRGGBB format) - similar to OpenGL vertex colors. You can use
0xAARRGGBB colors, but the alpha value will simply be ignored. To change the opacity use alpha.
See also:
@:value(true)dirty:Bool = true
Set this flag to true to force the sprite to update during the draw() call.
NOTE: Rarely if ever necessary, most sprite operations will flip this flag automatically.
@:value(RIGHT)facing:FlxDirectionFlags = RIGHT
Can be set to LEFT, RIGHT, UP, and DOWN to take advantage
of flipped sprites and/or just track player orientation more easily.
See also:
@:value(0)read onlyframeHeight:Int = 0
The height of the actual graphic or image being displayed (not necessarily the game object/bounding box).
framePixels:BitmapData
The current display state of the sprite including current animation frame,
tint, flip etc... may be null unless useFramePixels is true.
@:value(0)read onlyframeWidth:Int = 0
The width of the actual graphic or image being displayed (not necessarily the game object/bounding box).
read onlynumFrames:Int
The total number of frames in this image. WARNING: assumes each row in the sprite sheet is full!
read onlyoffset:FlxPoint
The position of the sprite's graphic relative to its hitbox. For example, offset.x = 10; will
show the graphic 10 pixels left of the hitbox. Likely needs to be adjusted after changing a sprite's
width, height or scale.
read onlyorigin:FlxPoint
WARNING: The origin of the sprite will default to its center. If you change this,
the visuals and the collisions will likely be pretty out-of-sync if you do any rotation.
pixels:BitmapData
This sprite's graphic / BitmapData object.
Automatically adjusts graphic size and render helpers if changed.
read onlyscale:FlxPoint
Change the size of your sprite's graphic.
NOTE: The hitbox is not automatically adjusted, use updateHitbox() for that.
WARNING: With FlxG.renderBlit, scaling sprites decreases rendering performance by a factor of about x10!
See also:
shader:FlxShader
GLSL shader for this sprite. Avoid changing it frequently as this is a costly operation.
4.1.0
.@:value(false)read onlyuseColorTransform:Bool = false
Whether or not to use a ColorTransform set via setColorTransform().
@:value(true)useFramePixels:Bool = true
Always true on FlxG.renderBlit. On FlxG.renderTile it determines whether
framePixels is used and defaults to false for performance reasons.
Defined by FlxObject
read onlyacceleration:FlxPoint
How fast the speed of this object is changing (in pixels per second). Useful for smooth movement and gravity.
@:value(FlxDirectionFlags.ANY)allowCollisions:FlxDirectionFlags = FlxDirectionFlags.ANY
Bit field of flags (use with UP, DOWN, LEFT, RIGHT, etc) indicating collision directions. Use bitwise operators to check the values stored here. Useful for things like one-way platforms (e.g. allowCollisions = UP;). The accessor "solid" just flips this variable between NONE and ANY.
@:value(0)angle:Float = 0
Set the angle (in degrees) of a sprite to rotate it. WARNING: rotating sprites decreases their rendering performance by a factor of ~10x when using blitting!
@:value(0)angularAcceleration:Float = 0
How fast the spin speed should change (in degrees per second).
@:value(0)angularVelocity:Float = 0
This is how fast you want this sprite to spin (in degrees per second).
@:value(IMMOVABLE)collisionXDrag:CollisionDragType = IMMOVABLE
Whether this sprite is dragged along with the horizontal movement of objects it collides with (makes sense for horizontally-moving platforms in platformers for example). Use values IMMOVABLE, ALWAYS, HEAVIER or NEVER
4.11.0
.@:value(NEVER)collisionYDrag:CollisionDragType = NEVER
Whether this sprite is dragged along with the vertical movement of objects it collides with (for sticking to vertically-moving platforms in platformers for example). Use values IMMOVABLE, ALWAYS, HEAVIER or NEVER
4.11.0
.collisonXDrag:Bool
DEPRECATED Whether this sprite is dragged along with the horizontal movement of objects it collides with (makes sense for horizontally-moving platforms in platformers for example).
Apart from having a weird typo, this has been deprecated for collisionXDrag, which allows more options.
@:value(null)debugBoundingBoxColor:Null<FlxColor> = null
Overriding this will force a specific color to be used for debug rect (ignoring any of the other debug bounding box colors specified).
@:value(FlxColor.BLUE)debugBoundingBoxColorNotSolid:FlxColor = FlxColor.BLUE
Color used for the debug rect if allowCollisions == NONE.
4.2.0
.@:value(FlxColor.GREEN)debugBoundingBoxColorPartial:FlxColor = FlxColor.GREEN
Color used for the debug rect if this object collides partially
(immovable in the case of FlxObject, or allowCollisions not equal to
ANY or NONE in the case of tiles in FlxTilemap).
4.2.0
.@:value(FlxColor.RED)debugBoundingBoxColorSolid:FlxColor = FlxColor.RED
Color used for the debug rect if allowCollisions == ANY.
4.2.0
.read onlydrag:FlxPoint
This isn't drag exactly, more like deceleration that is only applied
when acceleration is not affecting the sprite.
@:value(0)elasticity:Float = 0
The bounciness of this object. Only affects collisions. Default value is 0, or "not bouncy at all."
@:value(1)health:Float = 1
Handy for storing health percentage or armor points or whatever.
@:isVarheight:Float
The height of this object's hitbox. For sprites, use offset to control the hitbox position.
@:value(false)ignoreDrawDebug:Bool = false
Setting this to true will prevent the object's bounding box from appearing
when FlxG.debugger.drawDebug is true.
read onlylast:FlxPoint
Important variable for collision processing.
By default this value is set automatically during at the start of update().
@:value(1)mass:Float = 1
The virtual mass of the object. Default value is 1. Currently only used with elasticity during collision resolution. Change at your own risk; effects seem crazy unpredictable so far!
@:value(10000)maxAngular:Float = 10000
Use in conjunction with angularAcceleration for fluid spin speed control.
read onlymaxVelocity:FlxPoint
If you are using acceleration, you can use maxVelocity with it
to cap the speed automatically (very useful!).
@:value(defaultMoves)moves:Bool = defaultMoves
Set this to false if you want to skip the automatic motion/movement stuff (see updateMotion()).
FlxObject and FlxSprite default to true. FlxText, FlxTileblock and FlxTilemap default to false.
@:value(null)path:FlxPath = null
The path this object follows. Not initialized by default.
Assign a new FlxPath() object and start() it if you want to this object to follow a path.
Set path to null again to stop following the path.
See flixel.util.FlxPath for more info and usage examples.
@:value(true)pixelPerfectPosition:Bool = true
Whether or not the position of this object should be rounded before any draw() or collision checking.
pixelPerfectRender:Null<Bool>
Whether or not the coordinates should be rounded during rendering.
Does not affect copyPixels(), which can only render on whole pixels.
Defaults to the camera's global pixelPerfectRender value,
but overrides that value if not equal to null.
read onlyscrollFactor:FlxPoint
Controls how much this object is affected by camera scrolling. 0 = no movement (e.g. a background layer),
1 = same movement speed as the foreground. Default value is (1,1),
except for UI elements like FlxButton where it's (0,0).
solid:Bool
Whether the object collides or not. For more control over what directions the object will collide from,
use collision constants (like LEFT, FLOOR, etc) to set the value of allowCollisions directly.
@:value(FlxDirectionFlags.NONE)touching:FlxDirectionFlags = FlxDirectionFlags.NONE
Bit field of flags (use with UP, DOWN, LEFT, RIGHT, etc) indicating surface contacts. Use bitwise operators to check the values stored here, or use isTouching(), justTouched(), etc. You can even use them broadly as boolean values if you're feeling saucy!
@:value(FlxDirectionFlags.NONE)wasTouching:FlxDirectionFlags = FlxDirectionFlags.NONE
Bit field of flags (use with UP, DOWN, LEFT, RIGHT, etc) indicating surface contacts from the previous game loop step. Use bitwise operators to check the values stored here, or use isTouching(), justTouched(), etc. You can even use them broadly as boolean values if you're feeling saucy!
Defined by FlxBasic
@:value(idEnumerator++)ID:Int = idEnumerator++
A unique ID starting from 0 and increasing by 1 for each subsequent FlxBasic that is created.
@:value(true)alive:Bool = true
Useful state for many game objects - "dead" (!alive) vs alive. kill() and
revive() both flip this switch (along with exists, but you can override that).
cameras:Array<FlxCamera>
This determines on which FlxCameras this object will be drawn. If it is null / has not been
set, it uses the list of default draw targets, which is controlled via FlxG.camera.setDefaultDrawTarget
as well as the DefaultDrawTarget argument of FlxG.camera.add.
read onlycontainer:Null<FlxContainer>
The parent containing this basic, typically if you check this recursively you should reach the state

Returns:
this FlxSprite with loaded rotated graphic in it.
inlineresetFrame():Void
Helper method just for convenience, so you don't need to type
sprite.frame = sprite.frame;
You may need this method in tile render mode,
when you want sprite to use its original graphic, not the graphic generated from its framePixels.

therefore scrollFactor is ignored
Parameters:
worldPoint | The world coordinates. |
|---|---|
result | Optional arg for the returning point |
updateFramePixels():BitmapData
Retrieves the BitmapData of the current FlxFrame. Updates framePixels.
updateHitbox():Void
Updates the sprite's hitbox (width, height, offset) according to the current scale.
Also calls centerOrigin().
Defined by FlxObject
drawDebugOnCamera(camera:FlxCamera):Void
Override this function to draw custom "debug mode" graphics to the
specified camera while the debugger's drawDebug mode is toggled on.
Parameters:
Camera | Which camera to draw the debug visuals to. |
|---|
getMidpoint(?point:FlxPoint):FlxPoint
getPosition(?result:FlxPoint):FlxPoint
Returns the world position of this object.
Parameters:
result | Optional arg for the returning point. |
|---|
Returns:
The world position of this object.
getScreenPosition(?result:FlxPoint, ?camera:FlxCamera):FlxPoint
Returns the screen position of this object.
Parameters:
result | Optional arg for the returning point |
|---|---|
camera | The desired "screen" coordinate space. If |
Returns:
The screen position of this object.
hurt(damage:Float):Void
Reduces the health variable of this object by the amount specified in Damage.
Calls kill() if health drops to or below zero.
Parameters:
Damage | How much health to take away (use a negative number to give a health bonus). |
|---|
inlineinWorldBounds():Bool
Check and see if this object is currently within the world bounds - useful for killing objects that get too far away.
Returns:
Whether the object is within the world bounds or not.
isPixelPerfectRender(?camera:FlxCamera):Bool
Check if object is rendered pixel perfect on a specific camera.
inlineisTouching(direction:FlxDirectionFlags):Bool
Handy function for checking if this object is touching a particular surface.
Note: These flags are set from FlxG.collide calls, and get reset in super.update().
Parameters:
direction | Any of the collision flags (e.g. |
|---|
Returns:
Whether the object is touching an object in (any of) the specified direction(s) this frame.
inlinejustTouched(direction:FlxDirectionFlags):Bool
Handy function for checking if this object is just landed on a particular surface.
Note: These flags are set from FlxG.collide calls, and get reset in super.update().
Parameters:
direction | Any of the collision flags (e.g. |
|---|
Returns:
Whether the object just landed on (any of) the specified surface(s) this frame.
@:value({ inScreenSpace : false })@:access(flixel.group.FlxTypedGroup)overlaps(objectOrGroup:FlxBasic, inScreenSpace:Bool = false, ?camera:FlxCamera):Bool
Checks to see if some FlxObject overlaps this FlxObject or FlxGroup.
If the group has a LOT of things in it, it might be faster to use FlxG.overlap().
WARNING: Currently tilemaps do NOT support screen space overlap checks!
Parameters:
objectOrGroup | The object or group being tested. |
|---|---|
inScreenSpace | Whether to take scroll factors into account when checking for overlap.
Default is |
camera | Specify which game camera you want.
If |
Returns:
Whether or not the two objects overlap.
@:value({ inScreenSpace : false })@:access(flixel.group.FlxTypedGroup)overlapsAt(x:Float, y:Float, objectOrGroup:FlxBasic, inScreenSpace:Bool = false, ?camera:FlxCamera):Bool
Checks to see if this FlxObject were located at the given position,
would it overlap the FlxObject or FlxGroup?
This is distinct from overlapsPoint(), which just checks that point,
rather than taking the object's size into account.
WARNING: Currently tilemaps do NOT support screen space overlap checks!
Parameters:
x | The X position you want to check. Pretends this object (the caller, not the parameter) is located here. |
|---|---|
y | The Y position you want to check. Pretends this object (the caller, not the parameter) is located here. |
objectOrGroup | The object or group being tested. |
inScreenSpace | Whether to take scroll factors into account when checking for overlap.
Default is |
camera | Specify which game camera you want.
If |
Returns:
Whether or not the two objects overlap.
@:value({ axes : XY })inlinescreenCenter(axes:FlxAxes = XY):FlxObject
Defined by FlxBasic
getCameras():Array<FlxCamera>
The cameras that will draw this. Use this.cameras to set specific cameras for this object,
otherwise the container's cameras are used, or the container's container and so on. If there
is no container, say, if this is inside FlxGroups rather than a FlxContainer then the
default draw cameras are returned.
