How to convert mouse position to relative coords

[InTheProcess]

I am making a game that uses an isometric perspective. I have a formula that converts the tiles' actual positions to the relative coords. It doesn't seem to work the same with my mouse. The formula is below:

Code: Select all

	local a,b,c,d = x*0.5*w, -y*0.5*h, x*0.25*w, y*0.25*h
	local matrix = {d, -b, -c, a}
	--Using the inverse of the matrix
	for i,v in ipairs(matrix) do
		matrix[i] = (1/(a*d-b*c))*v
	end

Try to use some cam system / library, so you don't have to create calculations yourself.

There's a nice video by javidx9 channel that shows how to do this. https://www.youtube.com/watch?v=ukkbNKTgf5U&t=1s
