Isometric tile rendering
« on: June 12, 2022, 09:34:48 »
Hey everyone :)
I have been learning LWJGL & OpenGL. I'm trying to make an isometric game (See screenshots) But I can't get the rendering to work. I need my tiles to render from top to bottom and not from bottom to top so that the textures overlap. The tutorial series I was following said that they are rendered in the same order that they are added to the game, but this doesn't seem to be true. Can anyone help me get this rendering right?

If you need any classes/code snippets, please ask!
Window setup:
Code: [Select]
GLFWErrorCallback.createPrint(System.err).set();

// INIT GLFW
if(!glfwInit()) {
throw new IllegalStateException("Uh oh no GLFW init oops");
}

// CONFIGURE GLFW
glfwDefaultWindowHints();
glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE);
glfwWindowHint(GLFW_RESIZABLE, GLFW_TRUE);
glfwWindowHint(GLFW_MAXIMIZED, GLFW_TRUE);

// CREATE WINDOW
glfwWindow = glfwCreateWindow(this.width, this.height, this.title, NULL, NULL);
if(glfwWindow == NULL) {
throw new IllegalStateException("WAVING THRU NO WINDOW");
}

glfwSetCursorPosCallback(glfwWindow, MouseListener::mousePosCallback);
glfwSetMouseButtonCallback(glfwWindow, MouseListener::mouseButtonCallback);
glfwSetScrollCallback(glfwWindow, MouseListener::mouseScrollCallback);
glfwSetKeyCallback(glfwWindow, KeyListener::keyCallback);

// MAKE OPENGL
glfwMakeContextCurrent(glfwWindow);
// ENABLE MAGIC V-SYNC
glfwSwapInterval(1);

// MAKE THE WINDOW VISIBLE
glfwShowWindow(glfwWindow);

// important?
GL.createCapabilities();
glEnable(GL_BLEND);
glBlendFunc(GL_ONE, GL_ONE_MINUS_SRC_ALPHA);
