Hello,

 

I'm rendering a layer onto the back of the player all works fine, but the closer they look at there or someone else's layer the FPS just drops.

 

Looking at a friends about a block away i drop from 400fps to 28fps. The memory doesn't particularly rise though.

Without seeing your code, all we can do is guess at possible causes. Post your code.

main.java

 

package MinecraftCapesAndElytras;

import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPostInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import Render.PlayerInfo;

@Mod(modid = "MCE")
public class main {

@EventHandler
public void preInit(FMLPreInitializationEvent event) {
    
}

@EventHandler
public void load(FMLInitializationEvent event) {
	MinecraftForge.EVENT_BUS.register(new PlayerInfo());
	MinecraftForge.EVENT_BUS.register(new MainEventHandler());
}

@EventHandler
public void postInit(FMLPostInitializationEvent event) {
}

}

 

 

eventhandler

 

package MinecraftCapesAndElytras;

import Render.LayerCape;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraftforge.client.event.RenderLivingEvent;
import net.minecraftforge.client.event.RenderPlayerEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

public class MainEventHandler {

@SubscribeEvent
 public void onRenderEntity(RenderPlayerEvent.Pre event) {

 if(event.getEntity() instanceof EntityPlayer) {
	 EntityPlayer player = (EntityPlayer)event.getEntity();

	 event.getRenderer().addLayer(new LayerCape(event.getRenderer(), event.getEntity().getName()));

	 }
}
}

im guessing i would need to modify the event handler?

I'm just a little confused on how not to render every frame

You are adding a new layer... every frame. Don't.

 

I'm not sure how to "fix" this.

Ok, i've done this, seems to be working - thanks for your help!

 

 

package MinecraftCapesAndElytras;

import Render.LayerCape;
import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.entity.RenderPlayer;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraftforge.client.event.RenderLivingEvent;
import net.minecraftforge.client.event.RenderPlayerEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

public class MainEventHandler {

private boolean done = false;

@SubscribeEvent
 public void onRenderEntity(RenderPlayerEvent.Pre event) {

 if(event.getEntity() instanceof EntityPlayer && !done) {
	 EntityPlayer player = (EntityPlayer)event.getEntity();


		 event.getRenderer().addLayer(new LayerCape(event.getRenderer(), event.getEntity().getName()));

		 System.out.println("§e[MinecraftCapes]§r Added Cape Layer to Player");

		 done = true;

		 }
	}
}

 

There are two instances of

RenderPlayer

, one for the Steve model (thick arms) and one for the Alex model (thin arms). Your current code will only add the layer to the first one that renders.

 

In postInit, you should iterate through

RenderManager#getSkinMap

and add the layer to every

RenderPlayer

instance in the map. Don't use

RenderPlayerEvent

here at all.

AHAH! Done it - Thank you <3

 

 

	for(RenderPlayer render : Minecraft.getMinecraft().getRenderManager().getSkinMap().values()) {
		render.addLayer(new LayerCape(render, new PlayerInfo()));
		render.addLayer(new Deadmau5(render));
	}
