Custom block renderer without TileEntity

[shucke]

How can i render my custom model without the use of an TileEntity and TileEntitySpecialRenderer.

since i dont want my Block class to extends BlockContainer i want to know how to render a block without the tile entity.

i tried using the ISimpleBlockRenderingHandler but it gives me an error when i try to render my model.

 

this is the code im using the the ISimpleBlockRenderingHandler:

public boolean renderWorldBlock(IBlockAccess world, int x, int y, int z, Block block, int modelId, RenderBlocks renderer) {
	if(block instanceof IBlockRenderer){
		GL11.glPushMatrix();
		GL11.glBindTexture(GL11.GL_TEXTURE_2D, FMLClientHandler.instance().getClient().renderEngine.getTexture("/mods/hydrocraft/textures/models/gearBox.png"));
		GL11.glPushMatrix();
		GL11.glTranslatef((float)x + 0.5F, (float)y + 1.5F, (float)z + 0.5F);
		GL11.glRotatef(0, 0.0F, 1.0F, 0.0F);
		GL11.glScalef(1.0F, -1F, -1F);
		ModelGearBox model = new ModelGearBox();
		model.renderModel(0.0625F, 0, 1);
		GL11.glPopMatrix();
		GL11.glPopMatrix();
	}
        return false;
}

 

and this is the error im getting.

i tried returning true and that didnt make a difference either.

does any knows how to solve this problem?

"Already tesselating" means that the Tessellator.startDrawing was called several times, while in should be stopped by Tessellator.Draw before next call. That's all i can say

[shucke]

i know.

the Renderer is using the tessellator to draw the models.

however i want to use GL11 to draw the method since that is the way models are outputted trough techne.

[Naiten]

i know.

If you know, why are you asking and why u no fix the error?

Check your ModelGearBox.renderModel...

[Mazetar]

Just my two cents:

You don't need to exentd blockContainer to have a TE.

Just override the has TE and getTE methods.

[Mazetar]

Oh and one more thing:

and this is the error im getting.

Original problem solved then

 

New problem you want to use gl11 but not use tesselation? I understand the question but.. Why?

[redria7]

I'm interested in making a block with custom rendering without using a tile entity to avoid adding to lag if a player places lots of it in the world. I know it isn't a big problem, but tile entities do require more space and memory and so slow the game down. If I can make a custom rendered block without it being a tile entity, I'll be happy in a month or so when I start trying to tackle a new block I want.

So there is a reason, even if it isn't shucke's reason.

Very relevant night for me in the forums...

[Mazetar]

I didn't get what your answer had to do with my question about tesselation?

 

Also do you have any idea of the lagg introduced by using TEs compared to what system you are wanting to invent?

What error / performance hog inn TEs do you know off shich your system whont have?
