[1.20.4] Apply nausea wobble effect to the screen outside Nausea effect

[chxr]

So i know for a fact this has been asked before but Render stuff troubles me a little and i didnt find any answer for recent version. I have a custom nausea effect. Currently i add both my nausea effect and the vanilla one for the effect.

But the problem is that when I open the inventory, both are listed, while I'd only want mine to show up (both in the inv and on the GUI)

 

I've arrived to the GameRender (on joined/net/minecraft/client) and also found shaders on client-extra/assets/minecraft/shaders/post and client-extra/assets/minecraft/shaders/program but I'm lost. I understand that its like a regular screen, where I'd render stuff "over" the game depending on data on the server, but If someone could point to the right client and server classes that i can read to see how i can manage this or any tip would be apreciated

This honestly might just work for you

            final var options = Minecraft.getInstance().options;
            if(!hasMyEffect(player)) return; // TODO: You provide hasMyEffect

            float f = Mth.lerp(event.getPartialTick(), player.oSpinningEffectIntensity, player.spinningEffectIntensity);
            float f1 = ((Double)options.screenEffectScale().get()).floatValue();
            if(f <= 0F || f1 >= 1F) return;

            float p_282656_ = f * (1.0F - f1);
            final var p_282460_ = event.getGuiGraphics();
            int i = p_282460_.guiWidth();

            p_282460_.pose().translate((float)(-i) / 2.0F, (float)(-j) / 2.0F, 0.0F);
            float f4 = 0.2F * p_282656_;
            float f2 = 0.4F * p_282656_;
            float f3 = 0.2F * p_282656_;
            RenderSystem.disableDepthTest();
            RenderSystem.depthMask(false);
            RenderSystem.enableBlend();
            RenderSystem.blendFuncSeparate(GlStateManager.SourceFactor.ONE, GlStateManager.DestFactor.ONE, GlStateManager.SourceFactor.ONE, GlStateManager.DestFactor.ONE);
            p_282460_.setColor(f4, f2, f3, 1.0F);
            p_282460_.blit(new ResourceLocation("textures/misc/nausea.png"), 0, 0, -90, 0.0F, 0.0F, i, j, i, j);
            p_282460_.setColor(1.0F, 1.0F, 1.0F, 1.0F);
            RenderSystem.defaultBlendFunc();
            RenderSystem.disableBlend();
            RenderSystem.depthMask(true);
            RenderSystem.enableDepthTest();
            p_282460_.pose().popPose();
}

 

Note: Most of this is directly copied from GameRenderer as you pointed out you found.

The only thing you'll have to likely do is update the `oSpinningEffectIntensity` + `spinningEffectIntensity` variables on the player when your effect is applied. Which values should be there? Not 100% sure, might be a game of guess and check, but `handleNetherPortalClient` in LocalPlayer has some hard coded you might be able to start with.

Yeah i had something similar and the same problem is happening:It only triggers when in a gui (pause menu, inventory etc) is on the screen. So that was my main need of help. Do i need to make "a class to render the effect on", if that makes sense? Thanks for the render code though, with a few tweaks it will look amazing.

EDIT: If im not mistaken that's the expected result of the event used? But as I said this is my first time tinkering with player-side rendering.

Changing the event to RenderGuiEvent.post  kinda did the trick. If there is any more suitable events please tell me, and thanks for the help!
