Hey, I was having some fun with custom model rendering blocks and stuff and I wanted the center cube of the model to rotate. But however, the way I was doing it, the more blocks you have, the faster the spinning gets. I want to know how I would make that per-block or something.

 

Doing the actual rendering: https://github.com/mrkirby153/StevesBoats/blob/master/src/main/java/me/mrkirby153/StevesBoats/blocks/renderers/TileEntityBlockCrafterRenderer.java

Model Class: https://github.com/mrkirby153/StevesBoats/blob/master/src/main/java/me/mrkirby153/StevesBoats/models/ModelBlockCrafter.java

 

Let me know if I forgot something

Save the rotation value in the TileEntity. (not static)

 

Have the renderer read the value from the TileEntity, edit it as needed, and save back.

 

In my TileEntity:

public float rotation;

 

In my Renderer:

tile.rotation += 0.25F;

if (tile.rotation > 360) tile.rotation = 0F;

GL11.glRotatef(tile.rotation, 1F, 0F, 0F);

 

Do I need to save it to nbt or should I just add

public int rot = 0;

 

Also in my current setup do I rotate the box in the model class or the tile entity class?

I would say save it to NBT to be safe

 

@Override
public void writeToNBT(NBTTagCompound tag)
{
      tag.setInteger("rot", rot);
}

@Override
public void readFromNBT(NBTTagCompound tag)
{
      rot = tag.getInteger("rot");
}

No need to save it, its just visual.

Now I've long replaced my Techne models with OBJ's so lets see if I can get this from memory.

 

In TileEntityBlockCrafter.java add:

public float rotation; // you want this a float for better speed control

 

In ModelBlockCrafter.java add:

public void rotateCube(float rotation)
{
    this.CenterCube.rotateAngleY = rotation;
}

 

Now in TileEntityBlockCrafterRenderer.java before this.model.render:

((TileEntityBlockCrafter)te).rotation += 0.25F; // Change this number to change speed
if (((TileEntityBlockCrafter)te).rotation > 180) ((TileEntityBlockCrafter)te).rotation = -180F; // I believe Techne uses -180 to 180, instead of 0 to 360
this.model.rotateCube(((TileEntityBlockCrafter)te).rotation);

What program makes the obj files? Wait, yes I do I'll give that a shot when I have the chance
