Registering/Using ITickHandler

[Draco18s]

Alright, I can't figure this out.

 

I'm trying to add a new HUD item and I have a class that implements ITickHandler and I've registered it with the TickRegistry, but its methods are never called!

 

I have this in my main mod class

TickRegistry.registerTickHandler(new MyGUI(), Side.CLIENT);

 

And this is my GUI class

 

package draco18s.decay.client;

import java.util.EnumSet;

import org.lwjgl.opengl.GL11;

import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.FontRenderer;
import net.minecraft.client.gui.GuiIngame;
import net.minecraft.client.gui.ScaledResolution;

import cpw.mods.fml.common.ITickHandler;
import cpw.mods.fml.common.TickType;

public class OverhealGUI implements ITickHandler {
public Minecraft mc;


public OverhealGUI() {
	mc = Minecraft.getMinecraft();
}

@Override
public void tickStart(EnumSet<TickType> type, Object... tickData) {

}

@Override
public void tickEnd(EnumSet<TickType> type, Object... tickData) {
	System.out.println("Rendering GUI object");  //this never fires
	ScaledResolution scaledresolution = new ScaledResolution(mc.gameSettings, mc.displayWidth, mc.displayHeight);
	FontRenderer fontrenderer = mc.fontRenderer;
	int width = scaledresolution.getScaledWidth();
	int height = scaledresolution.getScaledHeight();
	mc.entityRenderer.setupOverlayRendering();
	if (type.equals(EnumSet.of(TickType.RENDER)))
	{
		onRenderTick();
	}
}

@Override
public EnumSet<TickType> ticks() {
	return null;
}

@Override
public String getLabel() {
	return null;
}

public void onRenderTick(){}
}

I don't quite get what you mean, but try looking through the Questology repo. Mainly the HUDOverlayHandler class (something like that) in the client package and some other ones that I can't remember at the time being... I know its some sort of tick handler.

[Draco18s]

Ok, I've got Questology's code, but I can't get anything to draw.

The only thing I can figure is that it's because net.minecraftforge.client.event.RenderGameOverlayEvent doesn't exist any more.

 

The function is being called, but nothing is getting drawn. :<

[Mew]

All I know is that you have to register it... like so:

 

MinecraftForge.EVENT_BUS.register(new HudOverlayHandler());

 

thats keeping to the questology code. Register this wherever you want it to I guess...

That part worked fine, the function is being called, but NOTHING IS DRAWN.

[Mew]

Haha.... Oops. I missed that

 

I'm not sure why, could you show what you do have? I know you have to have a picture that needs to be drawn onto the screen. I am just not quite sure, wait.

 

Did you get rid of the if statement in front of all the code in the drawing method? I know you most likely have, but its good to be sure... And if you can post the code, I can compare it to mine.

package draco18s.decay.client;

import org.lwjgl.opengl.GL11;

import draco18s.decay.PositiveDamage;
import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.Gui;
import net.minecraft.client.gui.GuiIngame;
import net.minecraft.client.gui.ScaledResolution;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraftforge.event.ForgeSubscribe;
import net.minecraftforge.client.event.RenderWorldLastEvent;

public class OverhealGUIHandler extends Gui {
private final Minecraft mc = Minecraft.getMinecraft();

@ForgeSubscribe
public void drawOverlay(RenderWorldLastEvent event) {
	System.out.println("Rendering");  //this prints
	mc.renderEngine.bindTexture("/mods/DecayingWorld/textures/gui/overheal.png");
	drawTexturedModalRect(244, 382, 0, 0, 162, 16);
}
}

[Mew]

hmm.... Maybe try keeping more of there code?

[Draco18s]

None of their code is relevant.  A large percentage of it has to do with Questology's...properties and variables.

Another good portion is drawing some text that I don't need

Of the remainder, it's what I have, plus some GUIscalar code, which shouldn't matter (except that it won't size my GUI object properly unless implemented).

[Mew]

Right. Ok, I don't then... All I know is that mine works

[SanAndreaP]

Right. Ok, I don't then... All I know is that mine works

Why do you extend Gui?

 

Scratch that, You need this: RenderGameOverlayEvent.Pre or RenderGameOverlayEvent.Post

not the RenderWorldLastEvent

*Cough*

Your forge is way outdated. Update.

 

Can't update very far, the mod I'm writing needs to work with another mod, which is not compatible past 644 (and I'm on 639).

[Noah_Beech]

Then get that guy to update his mod? It shouldn't be your problem...

[Draco18s]

He is updating, and when he updates I'll update my addon.  There's no point in updating my addon before the base mod updates, it would be unusable.

May I quickly ask, how you made a addon mod. I looked around and theres like nothing on it. I tried to do it myself but the mod I was doing an addon on the files were wierd, and things werent working just right. Is there any thing you saw that shows you how to do this?

The parent mod needs to have an API.  Very few do, but Mystcraft does (though it's not public; I was messing around doing neat stuff before I was given the API, and a lot of what I've done I've passed back to Mystcraft as starting points for things XCompWiz was going to implement eventually anyway).

 

You might be able to get away with decompiling the original and tying into its classes, then distributing your mod without those classes, but using the required-after dependency.  I haven't tried.  It'd be messy though and subject to easy breaking if the parent mod changes its structure, etc.
