This function allow us to add animation to dgs elements.

Change any property of dgs elements with animation effect.

Syntax

number/table dgsAnimTo ( element/table dgsElement, string propertyName, mixed value, string easing = "Linear", int duration [, int delay = 0, bool reverseProgress = false ] )

Required Arguments

  • dgsElement: The DGS element or a list of DGS elements to set animation to.
  • propertyName: The property you want to apply to,
  • value: Target value (should be a number when using built-in easing functions)
  • easing: The easing function to use for the interpolation (For More Detail :Easing), or your own easing function created by dgsAddEasingFunction.
  • duration: The time(ms) to finish the animation.

Optional Arguments

  • delay: The delay time before the animation start, can decrease the using of timer.
  • reverseProgress: Would you like the progress go from 0 to 1 or go from 1 to 0?

Returns

Returns an integer/table indicates the animation ID or a list of animation IDs if succeed, false otherwise.

Example

DGS = exports.dgs

if not DGS:dgsEasingFunctionExists("colorChange") then
	DGS:dgsAddEasingFunction("colorChange",[[
	--Predefined variable
	-- progress: from 0 to 1 , indicates the progress of the whole animation
	-- setting: a table {propertyName,targetValue,initialValue}
	-- self: the dgs element
	-- propertyTable: property table of the dgs element
		local _b,_g,_r,_a = bitExtract(setting[3],0,8),bitExtract(setting[3],8,8),bitExtract(setting[3],16,8),bitExtract(setting[3],24,8)
		local b,g,r,a = bitExtract(setting[2],0,8),bitExtract(setting[2],8,8),bitExtract(setting[2],16,8),bitExtract(setting[2],24,8)
		return tocolor(_r+(r-_r)*progress,_g+(g-_g)*progress,_b+(b-_b)*progress,_a+(a-_a)*progress)
	]])
end

image = DGS:dgsCreateImage(200,100,400,400,_,false,_,tocolor(0,0,0,255))
DGS:dgsAnimTo(image,"color",tocolor(200,100,50,255),"colorChange",5000)
