Parameters

Parameter	Type	Description
id	#number	The animation id
data	#table	A table of animation step values which can include (See Animation Step Table)

Animation Step Table

Key	Type	Value
key	#string	The data key for the animation step to be enacted upon.
rate	#string	The animation rate string: linear, easein, easeout, easeinout or bounce.
duration	#number	The length of the step (ms)
offset	#number	The offset from animation start where this step begins (ms).
from	#string, #number or #boolean	The value to start the animation at, if not specified the value is the current value of "key".
to	#string, #number or #boolean	The end point for the animation.

Example

    function create_animation(mapargs)
        local data = {}

        -- slide the x position 400 pixels over 2000 ms and auto-destroy
        -- it on completion
        id  = gre.animation_create(60, true)
        data["rate"] = "linear"
        data["duration"] = 2000
        data["offset"] = 0
        data["delta"] = 400
        data["key"] = "mylayer.mycontrol.grd_x"
        gre.animation_add_step(id, data)
    end
