>>>Warning: This feature requires pixel shader model 2_a<<<

This function creates a quadrilateral shader that can be used for dgs elements.

Syntax

element dgsCreateQuad( table corners [, int color = 0xFFFFFFFF, texture background = nil, bool colorOverwritten = true ] )
Example Rounded Rectangle

Required Arguments

  • corners : A table of the corners of the quadrilateral. The structure is as follows:
{
	{ float LeftTopX, float LeftTopY, bool relative },
	{ float RightTopX, float RightTopY, bool relative },
	{ float RightBottomX, float RightBottomY, bool relative },
	{ float LeftBottomX, float LeftBottomY, bool relative },
}

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

  • color: An int of the color of the quadrilateral.
  • background: A texture element of the background of the quadrilateral.
  • colorOverwritten: A bool indicates whether the final color will be overwritten by color or the product of render color and color (resultColor = render color * color) when rendering.

Returns

Returns a dgs-dxquad element (dgs Type)/ shader (element Type) if succeed, false otherwise

Example

DGS = exports.dgs --get exported functions from dgs

local quad = dgsCreateQuad({
	{0,0.1,true},	--Left Top
	{0.6,0.1,true},	--Right Top
	{0.9,0.9,true},	--Right Bottom
	{0.1,0.5,true},	--Left Bottom
},tocolor(255,255,255,100))
dgsQuadSetColorOverwritten(quad,false)

local btn = dgsCreateButton(500,400,100,100,"Button",false)
dgsSetProperty(btn,"image",quad)
