This is a fun and simple way to create isometric graphics in a 2D renderer. I made this with AWT and Swing.
To get the i and j positions (The positions relative to x and y) there is a simple bit of maths involved to calculate the new positions for the images.
l (y) isn't a real dimension in the rendering, I implemented it to work with layers. The l / y is just the same as the regular screen dimensions.
For Example:
TILESIZE = 32
x = 10
y = 3
z = 8
(float) new_x_i = x * 0.5 * TILESIZE (160)
(float) new_z_i = z * -0.5 * TILESIZE (128)
(int) i = new_x_i + new_z_i (288)
Round i to 0dp (whole number) - This is to make sure that there are no errors where you try and draw the image at a float value
(float) new_x_j = x * 0.25 * TILESIZE (80)
(float) new_z_j = z * 0.25 * TILESIZE (64)
(int) j = new_x_j + new_z_j (144)
Round j to 0dp (whole number)
(int) l = j - (y * (TILESIZE / 2)) (96)
Draw image at i, l (x, y)
