Example

This example will create detect area.

DGS = exports.dgs
da = DGS:dgsCreateDetectArea (400,300,400,200,false) -- Create Detect Area
DGS:dgsDetectAreaSetFunction(da,[[
	if mxRlt^2+myRlt^2 < 0.5 then
		return true
	end
]]) --Custom Detect Area function
DGS:dgsDetectAreaSetDebugModeEnabled(da,true)  --Set debug mode so that we can see where it is and how it looks like.

This example will create detect area with texture detecting function.

DGS = exports.dgs
tex = dxCreateTexture("yourTexture")
da = DGS:dgsCreateDetectArea (400,300,400,200,false) -- Create Detect Area
DGS:dgsDetectAreaSetFunction(da,tex) --Custom Detect Area function
DGS:dgsDetectAreaSetDebugModeEnabled(da,true)  --Set debug mode so that we can see where it is and how it looks like.
