[1.7.10] updateGui won't call!

HappyKiller1O1 · March 26, 2015

Ok so, I am trying to make it where the achievement thing that appears when you get an achievements appears also when you pick up my mods coin. So I found the class that makes the achievement thing happen and copied over then edited away unnecessary things. My problem is the updateGui, although my tick handler works just fine, won't seem to run. Someone please help!

Gui class:

You wrote:

if(!theGame.theWorld.isRemote)

That checks if it is Server World.. In rendering code!

You should remove that because rendering is only run on client side.

HappyKiller1O1 · March 26, 2015

See, when I change it I get a "OpenGL not found in current Thread" error. Meaning, it was trying to run it server side. This problem is confusing me beyond the point of reason.

HappyKiller1O1 · March 26, 2015

When I was looking through the other code of mods that use the Achievement Get overlay for something else; they never use it. So, I was thinking to just go around it like they do. Plus, I have no idea how to use that event.

Use it like any other event and register it in your client proxy to register it on your client side.

HappyKiller1O1 · March 26, 2015

But, how would I be able to make the overlay appear? Even by using that event my problem would still persist.

But, how would I be able to make the overlay appear? Even by using that event my problem would still persist.

Do this:

1. Make a class that extends Gui

2. In that class have the RenderGameOverlayEvent

3. Register the gui class in the ClientProxy

4. In the RenderGameOverlayEvent have whatever you want to do if your gui class says to(have a boolean doRender or something): rendering text, pictures,etc.

I don't see anything wrong with it at first glance. Run it and tell us if anything goes wrong.

So it all runs (the print outs show) but its not seeming to draw the box. Any input?

So it all runs (the print outs show) but its not seeming to draw the box. Any input?

Don't use drawTexturedModalRect use this:

public static void drawTexturedQuadFit(double x, double y, double width, double height, double zLevel){
	Tessellator tessellator = Tessellator.instance;
        tessellator.startDrawingQuads();
        tessellator.addVertexWithUV(x + 0, y + height, zLevel, 0,1); 
        tessellator.addVertexWithUV(x + width, y + height, zLevel, 1, 1);
        tessellator.addVertexWithUV(x + width, y + 0, zLevel, 1,0);
        tessellator.addVertexWithUV(x + 0, y + 0, zLevel, 0, 0);
        tessellator.draw();
}

And call that whenever you need to instead of the drawTexturedModalRect

I dont think it will help with your problem but ok..

Try putting the box at 0,0 and see if that works...

So, that worked! But, the UV is off. I'm not good with Tess so, how would I change the UV?

Abastro · March 26, 2015

The last two parameters of Tessellator#addVertexWithUV is the UV value, so you can change that.

HappyKiller1O1 · March 27, 2015

Ok, so it worked (after changing the texture to match the UV) but this happens:

Of course you have to modify the size.. It is simple, you just need to modify width and height.

HappyKiller1O1 · March 27, 2015

OMG! I am so stupid.

HappyKiller1O1 · March 27, 2015

Ok, so that works but, I can't draw text on the screen. D: Any input?

I forgot to add text to the strings. My last problem is my main one. I can't seem to call updateGui() when picking up my coin. Here are my classes:

Remove all Minecraft references from everything. (Only Gui class can use them, because it is client-sided)

1. When player picks-up coin, you will update value on server-side holder and send packet telling to open GUI and with new value.

2. On MessageHandler you will update client's value of Coin count and open gui.

3. Gui will use that value (client one).

Note: Since coins are per-player: USE IEEP (IExtendedEntityProperties)

http://www.minecraftforum.net/forums/mapping-and-modding/mapping-and-modding-tutorials/1571567-1-7-2-1-6-4-eventhandler-and

2nd post in thread.

Also:

if(!event.player.worldObj.isRemote) {
			guiCoin.setUnlockTime();
			System.out.println("CLIENT WORLD GOTTEN AND SET UNLOCK TIME");
		}

!isRemote - this is server.

isRemote - this is client.

Note 2:

Don't declare new ItemStack - just check item instance and add stack.stackSize

Uhm what?

public void onRenderExperienceBar(RenderGameOverlayEvent event)
{
    updateGui();
}

This will LITERALLY call updateGui() every frame-render. What is your problem?

Look at IEEP tutorial - you need to store coins per-player OR inside some static field.

I don't have time now to write all tutorial on this, but Skype: ernio333 I'll be ON in 14hours.

If you want to figure it faster - you hold 2 different values per client and server, server updates it and sends new value to client along with info that GUI should do whatever it does. Gui should be rendered ALWAYS (updateGui() is called every frame) and use clien-side value. E.g if you want something to display only when coins change you set some boolean in Gui class that will change to true after receiving packet of coin change, then to get it back to false you can use ClientTickEvent (i think it has phases, so check that also).

HappyKiller1O1 · March 27, 2015

My coinkeeper class uses player ID's in a HashMap to store the gold info so, no worries. But, I have used the tick handler and, no matter if it sets a boolean or not; the updateGui() is only called once. I put it in the render method as a test for the display so, ignore that. All I want it to do is, when you pick up a coin, like when getting an achievement; the box in the top right corner of the screen displays with the info.

Ernio · March 27, 2015

Didi you register that event? ;_;

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

...in client proxy.

Edit: EVENTS SHOULD BE IN SEPARATE CLASS.

	super.initialize();
	FMLCommonHandler.instance().bus().register(new TickHandlerClient());
	MinecraftForge.EVENT_BUS.register(new GuiCoinCollected(Minecraft.getMinecraft()));
	System.out.println("CLIENT PROXY REGISTERED ALL THINGS");
}
}

Like I said, it runs once but only once. These are the times I wish the creator of Java was a door away.

Did you specifically done this:

@SubscribeEvent
public void onRenderExperienceBar(RenderGameOverlayEvent event)
{
    updateGui();
}

Because if not, no wonder it is not passing:

if(event.isCancelable() || event.type != ElementType.EXPERIENCE) {
    		return;
    	}
