addAnimationByIndices(obj:String, name:String, prefix:String, indices:String, framerate:Int = 24)

Adds a new animation with the specified indices for the animation frames to play for the sprite object to use. If you want the looped version of this function use addAnimationByIndicesLoop(); all parameters and its use are the same.

obj - The sprite object tag name to be used.
name - The specified name of the animation to use.
prefix - The prefix name inside the xml file to be played.
frames - The indices indicating what animation frames to play in what order; Example: 1, 2, 3.
framerate - The speed in frames per second that the animation should play at; Defualt is: 24.

addOffset(obj:String, anim:String, x:Float, y:Float)

Adds a new offset value on each animation.

obj - The sprite object tag name to be used.
anim - The specified name of the animation to use.
x - The new x offset value of the animation.
y - the new y offset value of the animation.

Object Order Functions

setObjectOrder(obj:String, position:Int)

position - The new layer position to be set.

getObjectOrder(obj:String)

Gets the current layer position of the object current value; Returns a float number.

obj - The object tag name to be used.

objectsOverlap(obj1:String, obj2:String)

Checks if two objects are overlaping each-other; Returns a boolean.

obj1 - The first object tag name to be used.
obj2 - The second object tag name to be used.

Scale Functions

setGraphicSize(obj:String, x:Int, y:Int = 0, updateHitbox:Bool = true)

Sets the object graphic size by pixels; Not to be confused with scaleObject().

obj - The object tag name to be used.
x - The width value of the object to be set.
y - The height value of the object to be set.
updateHitbox - Whether it will update the object's dimension or hitbox; Defualt is true.

scaleObject(obj:String, x:Float, y:Float, updateHitbox:Bool = true)

Sets the object size by scale properties.

obj - The object tag name to be used.
x - The scale.x value of the object to be set.
y - The scale.y value of the object to be set.
updateHitbox - Whether it will update the object's dimension or hitbox; Defualt is true.

updateHitbox(obj:String)

Updates the object's dimension or hitboxes. Used this if you're changing scale of the object.

obj - The object tag name to be used.

Midpoint/Position Functions

getGraphicMidpointX(variable:String)

Gets the midpoint x value in graphics, of the object; Not to be confused with getMidpointX() function; Returns a float number.

variable - The object tag name to be used.

getGraphicMidpointY(variable:String)
