I am doing a Minecraft client like lunar, but when I click the HUD to modify the place of the "mod" or when I click randomly the game decides to crash. Here is my code for the HUDConfigScreen
package TrayardClient.gui.hud;

private int prevX, prevY;

for (IRenderer ren : registeredRenderers) {
if (!ren.isEnabled()) {
continue;
}
ScreenPosition pos = ren.load();
if (pos == null) {
pos = ScreenPosition.fromRelativePosition(0.5, 0.5);
}
adjustBounds(ren, pos);
this.renderers.put(ren, pos);
}
}

for(IRenderer renderer : renderers.keySet()) {
ScreenPosition pos = renderers.get(renderer);
renderer.render(pos);

I don't know what to do because I like to code (mostly in C# or python). I am a little bit new to Java. I can't post all the code here, but if you need the code of a certain class, please let me know.
