[1.5.1] Rendering Thrown Entities

[Draco18s]

I've got these lines in my main mod class

 

RenderingRegistry.registerEntityRenderingHandler(EntitySolidifier.class, new RenderSolidifier(solidifier));
RenderingRegistry.registerEntityRenderingHandler(EntityLifeBomb.class, new RenderLifebomb(lifebomb));

 

And I've got render classes (they're both the same, really):

 

package draco18s.decay.client;

import org.lwjgl.opengl.GL11;
import org.lwjgl.opengl.GL12;

import net.minecraft.client.renderer.Tessellator;
import net.minecraft.client.renderer.entity.Render;
import net.minecraft.entity.Entity;
import net.minecraft.entity.projectile.EntityPotion;
import net.minecraft.item.Item;
import net.minecraft.item.ItemPotion;
import net.minecraft.potion.PotionHelper;
import net.minecraft.util.Icon;

public class RenderSolidifier extends Render {
    private Item theItem;

public RenderSolidifier(Item i) {
	theItem = i;
}

public RenderSolidifier(Item i, int damage) {
	theItem = i;
}

@Override
public void doRender(Entity entity, double d0, double d1, double d2, float f, float f1) {
	System.out.println("Rendering?");  //this line never prints
	Icon icon = theItem.getIconFromDamage(0);
	if (icon != null)
        {
            GL11.glPushMatrix();
            GL11.glTranslatef((float)d0, (float)d1, (float)d2);
            GL11.glEnable(GL12.GL_RESCALE_NORMAL);
            GL11.glScalef(0.5F, 0.5F, 0.5F);
            loadTexture("/gui/items.png");//change this..?
            Tessellator tessellator = Tessellator.instance;
            render(tessellator, icon);
            GL11.glDisable(GL12.GL_RESCALE_NORMAL);
            GL11.glPopMatrix();
        }
}

private void render(Tessellator par1Tessellator, Icon par2Icon)
    {
        float f = par2Icon.getMinU();
        float f1 = par2Icon.getMaxU();
        float f2 = par2Icon.getMinV();
        float f3 = par2Icon.getMaxV();
        float f4 = 1.0F;
        float f5 = 0.5F;
        float f6 = 0.25F;
        GL11.glRotatef(180.0F - renderManager.playerViewY, 0.0F, 1.0F, 0.0F);
        GL11.glRotatef(-renderManager.playerViewX, 1.0F, 0.0F, 0.0F);
        par1Tessellator.startDrawingQuads();
        par1Tessellator.setNormal(0.0F, 1.0F, 0.0F);
        par1Tessellator.addVertexWithUV((double)(0.0F - f5), (double)(0.0F - f6), 0.0D, (double)f, (double)f3);
        par1Tessellator.addVertexWithUV((double)(f4 - f5), (double)(0.0F - f6), 0.0D, (double)f1, (double)f3);
        par1Tessellator.addVertexWithUV((double)(f4 - f5), (double)(f4 - f6), 0.0D, (double)f1, (double)f2);
        par1Tessellator.addVertexWithUV((double)(0.0F - f5), (double)(f4 - f6), 0.0D, (double)f, (double)f2);
        par1Tessellator.draw();
    }
}

 

 

Nothing renders.  I've even tried using the vanilla snowball renderer (which would work for my item).

 

What gives?  What am I missing?

This happened to me too...

 

Apparently when registering an entity you have to do a double registry using EntityRegistry.registerUniqueModID or something as well as registerMob or something like that. I can't remember at this point in time

[Draco18s]

If you could look that up, that'd be great.

Try adding this into preinit:

EntityRegistry.registerModEntity(EntityGrenade.class, "Grenade", 4, this, 350, 5, false);

Try adding this into preinit:

EntityRegistry.registerModEntity(EntityGrenade.class, "Grenade", 4, this, 350, 5, false);

 

 

That was the other one I was forgetting Its EntityRegistry.registerModEntity(EntityGrenade.class, "Grenade", 4, this, 350, 5, false); type thing instead of registerMob

Try adding this into preinit:

EntityRegistry.registerModEntity(EntityGrenade.class, "Grenade", 4, this, 350, 5, false);

 

Sweet, that worked (after I added a constructor that took only a world as a parameter).  Thanks!

Can you send me your projectile code? or thrown entity code as you put it? I can't get mine to work...

 

Also, does it actually render as visible? Whenever I try to make projectiles and such I only get an invisible entity

The entity is simple, just copy the EntitySnowball, there's really nothing special about it.  You just have to make the item spawn it (see ItemSnowball) and register it correctly (see this thread).
