Static methods
staticinlineaccelerateFromAngle(source:FlxSprite, radians:Float, acceleration:Float, maxSpeed:Float, resetVelocity:Bool = true):Void
Sets the x/y acceleration on the source FlxSprite so it will accelerate in the direction of the specified angle. You must give a maximum speed value (in pixels per second), beyond which the FlxSprite won't go any faster.

|---|---|
Radians | The angle in which the FlxPoint will be set to accelerate |
Acceleration | The speed it will accelerate in pixels per second |
MaxSpeed | The maximum speed in pixels per second in which the sprite can move |
ResetVelocity | Whether to reset the FlxSprite velocity to 0 each time |

staticaccelerateTowardsTouch(Source:FlxSprite, Touch:FlxTouch, Acceleration:Float, MaxSpeed:Float):Void
Sets the x/y acceleration on the source FlxSprite so it will move towards a FlxTouch at the speed given (in pixels per second) You must give a maximum speed value, beyond which the FlxSprite won't go any faster. If you don't need acceleration look at moveTowardsMouse() instead.
Parameters:

|---|---|
Touch | The FlxTouch on which to accelerate towards |
Acceleration | The speed it will accelerate in pixels per second |
MaxSpeed | The maximum speed in pixels per second in which the sprite can move |
staticcomputeVelocity(Velocity:Float, Acceleration:Float, Drag:Float, Max:Float, Elapsed:Float):Float
A tween-like function that takes a starting velocity and some other factors and returns an altered velocity.
Parameters:
Velocity | Any component of velocity (e.g. 20). |
|---|---|
Acceleration | Rate at which the velocity is changing. |
Drag | Really kind of a deceleration, this is how much the velocity changes if Acceleration is not set. |
Max | An absolute value cap for the velocity (0 for no cap). |
Elapsed | The amount of time passed in to the latest update cycle |
Returns:
The altered Velocity value.
staticmoveTowardsMouse(Source:FlxSprite, Speed:Float = 60, MaxTime:Int = 0):Void
Move the given FlxSprite towards the mouse pointer coordinates at a steady velocity If you specify a maxTime then it will adjust the speed (over-writing what you set) so it arrives at the destination in that number of seconds. Timings are approximate due to the way Flash timers work, and irrespective of SWF frame rate. Allow for a variance of +- 50ms. The source object doesn't stop moving automatically should it ever reach the destination coordinates.
Parameters:
Source | The FlxSprite to move |
|---|---|
Speed | The speed it will move, in pixels per second (default is 60 pixels/sec) |
MaxTime | Time given in milliseconds (1000 = 1 sec). If set the speed is adjusted so the source will arrive at destination in the given number of ms |
staticmoveTowardsObject(Source:FlxSprite, Dest:FlxSprite, Speed:Float = 60, MaxTime:Int = 0):Void
Sets the source FlxSprite x/y velocity so it will move directly towards the destination FlxSprite at the speed given (in pixels per second) If you specify a maxTime then it will adjust the speed (over-writing what you set) so it arrives at the destination in that number of seconds. Timings are approximate due to the way Flash timers work, and irrespective of SWF frame rate. Allow for a variance of +- 50ms. The source object doesn't stop moving automatically should it ever reach the destination coordinates. If you need the object to accelerate, see accelerateTowardsObject() instead Note: Doesn't take into account acceleration, maxVelocity or drag (if you set drag or acceleration too high this object may not move at all)
Parameters:
Source | The FlxSprite on which the velocity will be set |
|---|---|
Dest | The FlxSprite where the source object will move to |
Speed | The speed it will move, in pixels per second (default is 60 pixels/sec) |
MaxTime | Time given in milliseconds (1000 = 1 sec). If set the speed is adjusted so the source will arrive at destination in the given number of ms |
staticmoveTowardsPoint(Source:FlxSprite, Target:FlxPoint, Speed:Float = 60, MaxTime:Int = 0):Void
Sets the x/y velocity on the source FlxSprite so it will move towards the target coordinates at the speed given (in pixels per second) If you specify a maxTime then it will adjust the speed (over-writing what you set) so it arrives at the destination in that number of seconds. Timings are approximate due to the way Flash timers work, and irrespective of SWF frame rate. Allow for a variance of +- 50ms. The source object doesn't stop moving automatically should it ever reach the destination coordinates.
Parameters:
