Help with rendering GUI with MCP
I am trying to create a client using ModCoderPack for 1.8.8 but when I try to call displayGuiScreen the game crashes. I have code that waits for keypresses
That function is called in Minecraft.java
Here is the entire code for the Client class
Code:
public void onKeyPressed(GameSettings gs) {
if(gs.jbClientToggleMenu.isKeyDown()) {
this.mc.displayGuiScreen(new ModManager());
}
}
Code:
else
{
jbclient.onKeyPressed(this.gameSettings); // <-=
if (k == 1)
{
this.displayInGameMenu();
}
Code:
public class Client {
private final Minecraft mc = Minecraft.getMinecraft();
private GameSettings gameSettings = new GameSettings();
public static String clientName = "jbClient";
public static String clientVersion = "0.01";
public static final ModManager modManager = new ModManager();
public static final Logger logger = LogManager.getLogger();
public void onKeyPressed(GameSettings gs) {
if(gs.jbClientToggleMenu.isKeyDown()) {
this.mc.displayGuiScreen(new ModManager());
}
}
}
Code:
