I have made a potion for my mod and I have also made its effect, the only problem is I don't know how to make it render a custom icon when it is applied to the player. I have found a way to do it in normal minecraft when a gui is not open with the RenderGameOverlayEvent. How would I make it so that when the players inventory is open my effect renderer (which only has a different texture btw) will render over the existing mine craft potion buff renderer.

 

Or even better is there a way I can simply change the mine craft inventory texture without a resource pack.

yeah technicly you could set to a different render target before drawing the gui and render your texture/image/wtv there too

 

or if thats chinese / too complicated you can also (and its a better option)

 

make a TickHandler client side and render there

make a TickHandler client side and render there

 

I tried something like that, but the only problem is I don't know how to make something render outside of a render class.

you do the exact same thign, there no magic there

 

back in the days, before RnederGameOverlayEvent was created, i was rendering my mana bar in a TickHandler

when the RenderGameOverlayEvent arrived, i copy pasted my code in a @ForgeSubscribe event method

I got some code for you:

import net.minecraftforge.client.event.RenderGameOverlayEvent;
import net.minecraftforge.client.event.RenderGameOverlayEvent.ElementType;
import net.minecraftforge.event.ForgeSubscribe;
//maybe some imports are missing... I hope not, respond if I'm wrong or fix it yourself
public class YourRenderer()
{
public YourRenderer()
{
//Whatever you need else
MinecraftForge.EVENT_BUS.register(this); //You can/should/may do this after you created an instance of the class anywhere you
								//like
}
@ForgeSubscribe
public void onRenderEvent(RenderGameOverlayEvent.Post postRender) //You wanted to render afterwards
{
if(postRender.type!=ElementType.ALL) return; //This renders it really last. You can select another ElementType if you like.
//your render code
}
}

you do the exact same thign, there no magic there

Okay, that kind of works, but I use methods like drawTexturedModalRect that only work if the class it is inside extends Gui.

then do it by hand

code example because youll end up asking for it anyway

 

Tessellator tess = Tessellator.instance;
Minecraft.getMinecraft().renderEngine.bindTexture("path/to/texture");// or bind ressource if in 1.6+
tess.startDrawingQuads();
tess.setColorOpaque_F(1, 1, 1);
tess.addVertexWithUV(startX, startY, 0, 0, 0);
tess.addVertexWithUV(startX, startY+height, 0, 0, 1);
tess.addVertexWithUV(startX+width, startY+height, 0, 1, 1);
tess.addVertexWithUV(startX+xSize, startY, 0, 1, 0);
tess.draw();

you can still use the methods from your gui-extending class even when MC isn't 'displaying' that GUI -- this is how I render health bars for my vehicles in an overlay.

 

in your client tick handler, have a reference to your gui-extending object, and onTick() just call the render methods for (from/within) your GUI.

 

Tick Handler maybe great for some purposes but in my opinion @ForgeSubcribe-method is better as you can hook in everywhere you want (for example after the healthbar or before the hungerbar w s e). Just sayin

Okay, put it in a client tick handler and it works. Kind of. It keeps randomly blinking and I'm not sure how to fix that.

same thing happened to me, print your code i dont remember the answer

My client tick handler. Do you need anything else?

I would suppose not to use TickType.PLAYER but TickType.RENDER. Everything should work smoother

oh its not the same problem, mine was because i was rendering on tickEnd, you should maybe leave that method empty as your computer will work twice as hard for the same resutl

That fixed it thanks! Although, however, now the text decided to not render

are you rendering the text AFTER the rest ? basicly if you render it first, the rest will show up in fron of it and you wont see it

Yes
