Hey I'm making a small indie game project but have hit a bit of a road block. My maths is not great and until now i been doing fine but have got stuck. I'm trying to calculate how many tiles fit within an area in an isometric angle - so that no empty spaces are left. Lets say the area is: Width : 1200 height : 600 The isometric tiles are: width: 64 height: 32 Now I first tried: (area width / tile width) * (area height / tile height) But that doesn't work because it means each 4 corners are empty spaces. Which means this is not the "maximum" amount of tiles... so does any one know the formula to working it out ?
