[1.7.2] Drawing a string on the top-left corner of the screen.

[coolboy4531]

I have gotten it to work in 1.6.2 before, but updating it to 1.7.2? pain in the ass.

 

Let me explain my situation, everything works fine, got my events working and tested with [system.out.println("test")]

Whenever I replace System.out.println("test") and run it with my thingy I'm using, it creates GL11 errors.

 

Is it because I changed the event to boolean, because I'm transferring my ModLoader mod to Forge during 1.7.2 with no ModLoader inside Forge... which I used the "onTickInGame" method, but I really don't know how to transfer a boolean to a void...

Coding:

 

Event Class:

@SubscribeEvent
public boolean onWorldTick(TickEvent.WorldTickEvent event)
{
	Minecraft mc = Minecraft.getMinecraft();
	Tracker trck = Tracker.wl; //wl = this (Tracker) 
	trck.doFunction(); //[something with this too in crash report]
	return true;
}

 

doFunction method:

public boolean doFunction()
    {
    	Minecraft minecraft = Minecraft.getMinecraft();
        if (minecraft == null || minecraft.currentScreen != null || minecraft.gameSettings == null || minecraft.gameSettings.showDebugInfo)
        {
            return true;
        }
        String s = (new StringBuilder()).append("No mobs tracked! D: (Press ").append(minecraft.gameSettings.getKeyDisplayString(key1.func_151463_i())).append(" to enable/disable this mod.)").toString();
        if (membyte != null)
        {
            s = (new StringBuilder()).append("Mob Info: [").append(MobStatus.infoList()).append("]\n").toString();
            s = (new StringBuilder()).append(s).append("At Coords: X: ").append((int)MobStatus.cur_posX).append(" Y: ").append((int)MobStatus.cur_posY).append(" Z: ").append((int)MobStatus.cur_posZ).append("\n").toString();
            EntityPlayerSP entityplayersp = minecraft.thePlayer;
            
            if (entityplayersp != null)
            {
                s = (new StringBuilder()).append(s).append("X~Away: ").append((int)(MobStatus.cur_posX - ((EntityPlayer)(entityplayersp)).posX)).append(" Y~Away: ").append((int)(MobStatus.cur_posY - ((EntityPlayer)(entityplayersp)).posY)).append(" Z~Away: ").append((int)(MobStatus.cur_posZ - ((EntityPlayer)(entityplayersp)).posZ)).toString();
            }
        }
        int i = 0;
        byte byte0 = 7;
        String as[] = s.split("\n");
        int j = as.length;
        int k = 0;

        do
        {
            if (k >= j)
            {
                break;
            }
            String s1 = as[k];
            if (++i > byte0)
            {
                break;
            }
            minecraft.fontRenderer.drawStringWithShadow(s1, 23, 10 + i * 10, 0xffffff); //[main error]
            k++;
        }
        while (true);

        canChangeSettings++;

        if (!coords)
        {
            return true;
        }

        if (minecraft.theWorld == null)
        {
            return true;
        }

        if (membyte2 != null && MobStatus.isMobDead)
        {
            MobStatus.curMob = null;
        }

        MobStatus.curMob = null;
        boolean flag = false;
        Iterator iterator = minecraft.theWorld.loadedEntityList.iterator();

        do
        {
            if (!iterator.hasNext())
            {
                break;
            }

            Object obj = iterator.next();

            if (obj instanceof EntityMob)
            {
                if (MobStatus.curMob != null && obj.equals(MobStatus.cur_Mob))
                {
                    flag = true;
                }

                if (MobStatus.curMob == null || minecraft.thePlayer != null && minecraft.thePlayer.getDistanceToEntity((EntityMob)obj) < minecraft.thePlayer.getDistanceToEntity(MobStatus.curMob))
                {
                    MobStatus.curMob = (EntityMob)obj;
                }
            }
        }
        while (true);
     }
        return true;
    }

Any help will be appreciated.

Thanks

The biggest help you can get is by your own doing: learn how to code.

You make nearly one mistakes per line at the moment.

[Bantasaurusrex]

If you want to draw a string why are you using onWorldTick? you should use TickEvent.RenderTickEvent. to render and TickEvent.WorldTickEvent for logic (what I can see your trying to track mobs I think), like GotoLink said look at your code there are errors there.

This.

 

Also, your error happens at

 

at com.coolboy4531.Tracker.doFunction(Tracker.java:115)

 

Go there.

 

Figure out why.

 

You didn't even include enough code of that class for me to locate that line so I couldn't help you if I wanted to, which I don't, because you're making mistakes left and right (why does doFunction() return a boolean if that boolean is ignored?  Why do you do a Minecraft.getMinecraft() both before calling the function and inside the function instead of passing it?  Or better yet, what purpose is it being put to in the event listener class?  StringBuilder().append().toString()?  Was

String s = "I need " + a_variable + " stringified"

wasn't good enough?)
