I'm doing the render things. Don't know why after the entity spawn, the render rendered for a few ticks and didn't work.... The render is not called after the first few ticks.

code is like

The entity

private int livetime;
public EntityMagicRenderTest(World par1World, double x, double y, double z) {
	super(par1World);
	this.setPosition(x,y,z);
	livetime = 200;
}
public EntityMagicRenderTest(World par1World, double x, double y, double z, int deadline) {
	super(par1World);
	this.setPosition(x,y,z);
	livetime = deadline;
}

public EntityMagicRenderTest(World par1World) {
	super(par1World);
}
@Override
protected void entityInit() {
}

@Override
public void onUpdate() {
	super.onUpdate();
	--livetime;
	if (livetime <= 0) {
		this.setDead();
	}
	//this.setPosition(this.posX, this.posY, this.posZ);

        
	if (!this.worldObj.isRemote && livetime % 20 == 0) {
		System.out.println("livetime = " + livetime);
		System.out.println(this.posX + " " + this.posY + " " + this.posZ);
	}
}

 

the renderer:

 

	public void doRender(Entity entity, double d0, double d1, double d2,
		float f, float f1) {


	System.out.println("try render");

	GL11.glPushMatrix();
	bindEntityTexture(entity);
        GL11.glTranslatef((float)d0, (float)d1, (float)d2);


	GL11.glRotatef(180F -renderManager.playerViewY, 0.0F, 1.0F, 0.0F);
    	GL11.glRotatef(-renderManager.playerViewX, 1.0F, 0.0F, 0.0F);
    	
        Tessellator t = Tessellator.instance;
        t.startDrawingQuads();
        t.setNormal(0, 0, 0);
        
        t.addVertexWithUV(-0.5, -0.5, 0.0, 0, 0);
        t.addVertexWithUV(-0.5, 0.5, 0.0, 0, 1);
        t.addVertexWithUV(0.5, 0.5, 0.0, 0.5, 1);
        t.addVertexWithUV(0.5, -0.5, 0.0, 0.5, 0);
        
        t.addVertexWithUV(-0.5, -0.5, 0.0, 0, 0);
        t.addVertexWithUV(0.5, -0.5, 0.0, 0.5, 0);
        t.addVertexWithUV(0.5, 0.5, 0.0, 0.5, 1);
        t.addVertexWithUV(-0.5, 0.5, 0.0, 0, 1);
        
        t.draw();
        
        GL11.glPopMatrix();
}

 

I've successed for a time.. But suddenly it didnt work again..

well to me that seems normal as you have a liveTime variable and you kill your entity when its under 0, maybe i missed something,

 

does it stop rendering BEFORE it dies ?

 

remember that server and client are 2 different program, maybe if youre testing with an actual client + server the server tick faster then the client or vice versa so there is a desynchronisation, in this case i would recommend DataWatching your livetime

I'm new to render. So it's just for test so I simply set the livetime. I know the difference between the client and the server.

 

And yes, it stop rendering BEFORE it die as I could see messages in the onUpdate() method of the entity.

 

And I try to delete "--livetime;". But nothing change. The "rendered entity" appear 2-3 ticks and then disappear while the entity is still alive.

ok, do you know for a fact that it hasn't moved extremmelly far? like can you hit it after it vanishes ?

 

 

how is it spawned ?

 

I use a item and spawn it in the position where the player stand. And as there is almost nothing in the entity, I don't know if I can hit it, I'll try later. In my success case I try to make it move and succeed, and now I delete the code about its movement, so I think it could not move extremmelly far.

I try to collide with it and succeed in the expect position.

I think the client's livetime variable is never set so it stays at 0. Then in the update method this line will (also) trigger on the client:

if (livetime <= 0) {
		this.setDead();
	}

 

Solution would be to add a server check:

if (!worldObj.isRemote && livetime <= 0) {
		this.setDead();
	}

That's it.. It seems I don't know about the difference between server and client well :'( :'(

Thx
