[Closed] Projection Matrix to Game Engine

Ok the game engine has y and Z swapped around as per normal.

this is the code im running on a selected camera to get a projection matrix. It doesnt seem to be working.

If anyone has any experience with this could they give me some help?

-- Get Projection Matrix

clearListener()
myUnits = units.MetricType
units.MetricType = #centimeters

mapped fn fnMatrixMaxToEngine valMatrix = --takes a matrix output a string
(
	mRow1 = valMatrix.row1

		--if mRow1[i] < 0.00001 do
		--	mRow1[i] = 0
			
	mRow2 = valMatrix.row2 

	--for i = 1 to 3 do
		--if mRow2[i] < 0.00001 do
		--	mRow2[i] = 0
	
	mRow3 = -(valMatrix.row3) -- invert this as cam faces backwards!

	--for i = 1 to 3 do
		--if mRow3[i] < 0.00000001 do
		--	mRow3[i] = 0
			
	mTranslation = valMatrix.translation
	print mTranslation
