TESR Model Lag

[tattyseal]

Hello, I am making a mod with a block with 16*16 cubes in a block so 256 cubes in the model, and when I try to render it, it causes the fps to drop the more that are placed, this is caused by the for loop I think.  I don't know if there is an alternative to this. Thanks.

 

Also, the cubes have to be individual, because I am going to have a gui, so the user can remove cubes and path redstone down them etc. So I need each cube to be removable

 

Model Code:

package com.tattyseal.circuits.client.model;

import net.minecraft.client.model.ModelBase;
import net.minecraft.client.model.ModelBiped;
import net.minecraft.client.model.ModelRenderer;

/**
* Created by Toby on 04/11/2014.
*/
public class ModelCircuitBoard extends ModelBase
{
    public ModelRenderer[] etchings;
    public ModelRenderer base;

    public ModelCircuitBoard()
    {
        etchings = new ModelRenderer[16 * 16 + 1];

        int id = 0;

        for(int x = 0; x < 16; x++)
        {
            for(int z = 0; z < 16; z++)
            {
                etchings[id] = new ModelRenderer(this, 0, 0);

                //* Creates a textured box. Args: originX, originY, originZ, width, height, depth, scaleFactor.
                etchings[id].addBox(x, 0, z, 1, 1, 1, 0.0f);

                id++;
            }
        }
    }
}

 

Renderer Code:

package com.tattyseal.circuits.client.renderer;

import com.tattyseal.circuits.client.model.ModelCircuitBoard;
import net.minecraft.client.model.ModelRenderer;
import net.minecraft.client.renderer.tileentity.TileEntitySpecialRenderer;
import net.minecraft.tileentity.TileEntity;
import org.lwjgl.opengl.GL11;

/**
* Created by Toby on 04/11/2014.
*/
public class RenderCircuitBoard extends TileEntitySpecialRenderer
{
    public ModelCircuitBoard model;

    public RenderCircuitBoard()
    {
        this.model = new ModelCircuitBoard();
    }

    @Override
    public void renderTileEntityAt(TileEntity tile, double x, double y, double z, float scale)
    {
        GL11.glDisable(GL11.GL_LIGHTING);
        GL11.glPushMatrix();

        GL11.glTranslated(x, y, z);

        for(ModelRenderer renderer : model.etchings)
        {
            if(renderer != null) renderer.render(0.0625f);
        }

        GL11.glPopMatrix();
        GL11.glEnable(GL11.GL_LIGHTING);
    }
}

You realize that one of your TEs is worth 3072 triangles, right?

A standard block is 12...

[tattyseal]

Yeah, like I said, I need a new way to do it

[SanAndreaP]

So your 16x16 structure is placed and removed at once?

If so, why not making a model with only one block which occupies that space? Then have one TE render it and the rest just won't render anything.

[jabelar]

Maybe I don't quite understand the structure your trying to make, but what is specific reason you need TESR?  What is the rendering doing that needs to update every tick?

 

Otherwise can't this be done with normal custom blocks?  Why can't you just place blocks like normal and "move" them by destroying and swapping block placements?

 

Also is an ISBRH useful for what you want to do -- are the changes in the rendering only when blocks are "moved"?

[Abastro]

I think ISBRH is appropriate for this purpose, as jabelar said.

You can use worldObj.markBlockForUpdate(xCoord, yCoord, zCoord) when it is changed.

It will call the render to update block rendering.

Hi

 

If you don't need your model to update every frame, you could compile your model to a render list.  That is quite a bit faster.  256*6 faces takes very little time at all to render.

 

For example that's what I used in this mod to show the blocks being copied.

Alternatively, you could create a renderlist for a cube, then render the renderlist at each cube location (using glTranslate) using your for loop.  That's probably much faster than the model renderer.

Forgot to mention - what you're doing sounds very similar to how vanilla takes an item's icon and gives it thickness when rendering in the hand.  It might help to look at that (i.e. each of your cubes is one texel of the item icon).

After working on a 3D game, I should have thought of a render list I will try that. Thanks
