[SOLVED] [1.9] Render Player upside down (dinnerbone)

[james090500]

Hello, me again

 

I'm trying to render the player and other players upside down if they have a certain username.

 

 

package RenderPlayer;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.List;

import Config.getOS;
import net.minecraft.client.entity.AbstractClientPlayer;
import net.minecraft.client.renderer.GlStateManager;
import net.minecraft.entity.Entity;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.player.EnumPlayerModelParts;
import net.minecraft.util.text.TextFormatting;
import net.minecraftforge.client.event.RenderPlayerEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;


public class UpsideDown {

@SubscribeEvent
public void doRender(RenderPlayerEvent event) {
	rotateCorpse(event.getEntity());
}

public void rotateCorpse(Entity bat) {
   if (System.getProperty("java.version").startsWith("1.8")) {
        try{
            String s = TextFormatting.getTextWithoutFormattingCodes(bat.getName());
            List<String> users = Files.readAllLines(Paths.get(getOS.OS + "/capes/Dinnerbone.txt"));
          	if (users.contains(s)|| s.equals("james090500") || s.equals("Grumm") && (!(bat instanceof EntityPlayer) || ((EntityPlayer)bat).isWearing(EnumPlayerModelParts.CAPE)))
            {
				GlStateManager.translate(0.0F, bat.height + 0.1F, 0.0F);
        			GlStateManager.rotate(180.0F, 0.0F, 0.0F, 0.0F);
        			GlStateManager.rotate(180.0F, 0.0F, 180.0F, 0.0F);
            }
        } catch (IOException e) {}
    }
}
}

 

 

and i am initialising like this:

 

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

}

 

 

However, this turns ALL entitys upside down sadly. like this -

 

 

[Ernio]

Use Pre and Post sub-events. In pre you perform rotation. In Post you need to rotate back to 0.

 

P.S: You should move client-only (rendering) events into ClientProxy (meaning - register them via proxy call)

Point of interest:

Something like this?

 

 

public class UpsideDown {

@SubscribeEvent
public void doRender(RenderPlayerEvent.Pre event) {
	PreRotateCorpse(event.getEntity());
}

public void PreRotateCorpse(Entity bat) {
   if (System.getProperty("java.version").startsWith("1.8")) {
        try{
            String s = TextFormatting.getTextWithoutFormattingCodes(bat.getName());
            List<String> users = Files.readAllLines(Paths.get(getOS.OS + "/capes/Dinnerbone.txt"));
          	if (users.contains(s)|| s.equals("james090500") || s.equals("Grumm") && (!(bat instanceof EntityPlayer) || ((EntityPlayer)bat).isWearing(EnumPlayerModelParts.CAPE)))
            {
				GlStateManager.translate(0.0F, bat.height + 0.1F, 0.0F);
        			GlStateManager.rotate(180.0F, 0.0F, 0.0F, 0.0F);
        			GlStateManager.rotate(180.0F, 0.0F, 180.0F, 0.0F);
            }
        } catch (IOException e) {}
    }
}

@SubscribeEvent
public void doRender(RenderPlayerEvent.Post event) {
	PostRotateCorpse(event.getEntity());
}

public void PostRotateCorpse(Entity bat) {
   if (System.getProperty("java.version").startsWith("1.8")) {
        try{
            String s = TextFormatting.getTextWithoutFormattingCodes(bat.getName());
            List<String> users = Files.readAllLines(Paths.get(getOS.OS + "/capes/Dinnerbone.txt"));
          	if (users.contains(s)|| s.equals("james090500") || s.equals("Grumm") && (!(bat instanceof EntityPlayer) || ((EntityPlayer)bat).isWearing(EnumPlayerModelParts.CAPE)))
            {
				GlStateManager.translate(0.0F, bat.height + 0.1F, 0.0F);
        			GlStateManager.rotate(0.0F, 0.0F, 0.0F, 0.0F);
        			GlStateManager.rotate(0.0F, 0.0F, 0.0F, 0.0F);
            }
        } catch (IOException e) {}
    }
}

}

 

 

Also my mod is client side only

[Ernio]

1st of all - don't ever perform checks like you do (files and other comprasions like version check) every FRAME!

Make some boolean that is set from mod pre-init/init.

And don't ask - just test it. I think rotation is collective so you have to rotate twice 180, but I don't remember.

[james090500]

With this, the character rotates fine, but again other entitys with it, i'll try your other suggestions now

[Ernio]

From what I remember the basic concept is:

 

pre(Pre event)
{
    GL11.pushMatrix()
    /// modify states
    // do stuff
}
post(Post event)
{
    // do stuff
    // revert states
    GL11.popMatrix()
}

 

The reason you have to get state back in place is beacuse entities are rendered sequentially so if you change state and don't revert it - all next ones are also affected.

 

I might be wrong as this is 1.9 and last time I was working with such things was early/mid 1.8.

If wrong I am - looking forward to learn this as I will be soon getting back to dev (exams now)

[james090500]

Yes, you are most definitely correct.
