[Solved] Rotation of a model resets after reloading world

[ninjapancakes87]

I have a block I am making, and it has a custom model.  The model is two blocks long, so when you place it, it rotates according to the direction you are facing.  The problem is, when I reload the world, it resets the rotation of the model, but not the rotation of the block itself.  Does anybody know how to fix this?

TileEntityCannon:

 

package ninjapancakes87.civilwar.block.cannon;

import java.util.logging.Level;
import java.util.logging.LogRecord;

import cpw.mods.fml.common.FMLLog;

import net.minecraft.block.Block;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.server.MinecraftServer;
import net.minecraft.tileentity.TileEntity;
import net.minecraftforge.common.ForgeDirection;
import ninjapancakes87.civilwar.CivilWar;

public class TileEntityCannon extends TileEntity{
public byte rotation;
public Block block;
public TileEntityCannonRenderer TErender;

@Override
    public void readFromNBT(NBTTagCompound nbtTagCompound) {
	super.readFromNBT(nbtTagCompound);
	this.setRotation(nbtTagCompound.getByte("rotation"));
	CivilWar.CwLogger.log(Level.INFO, "Read rotation: " + this.rotation);
}
@Override
    public void writeToNBT(NBTTagCompound nbtTagCompound) {
	super.writeToNBT(nbtTagCompound);
	nbtTagCompound.setByte("rotation", this.getRotation());
	CivilWar.CwLogger.log(Level.INFO, "Write rotation: " + this.rotation);
}
public byte getRotation(){
	return this.rotation;
}
public void setRotation(byte par1){
	this.rotation = par1;
}
}

 

TileEntityCannonRenderer:

 

package ninjapancakes87.civilwar.block.cannon;

    /** The cannon model */
    private Cannon model;
    
    public short scale;
    
    /** Instance of renderManager, super one is not visible*/

    public TileEntityCannonRenderer()
    {
    	this.model = new Cannon();
    }
    /**

     */
@Override
public void renderTileEntityAt(TileEntity tileentity, double d0, double d1, double d2, float f) {
	TileEntityCannon cannonTE = (TileEntityCannon)tileentity;
	GL11.glPushMatrix();
	GL11.glTranslatef((float) d0 + 0.5F, (float) d1 + 1.5F, (float) d2 + 0.5F);
	GL11.glScalef(1.0F, -1F, -1F);
	byte rotation = cannonTE.getRotation();
	if(rotation == 2){
            scale = -90;
        }

        if(rotation == 3){
            scale = 90;
        }

        if(rotation == 4){
            scale = 180;
        }

        if(rotation == 5){
            scale = 0;
        }
        GL11.glRotatef(scale, 0.0F, 1.0F, 0.0F);
	GL11.glRotatef(90, 0, 1.0F, 0);
	this.func_110628_a(texture);
	this.model.render((Entity)null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);
	GL11.glPopMatrix(); 
}
public void rotate(byte rotation){
	if(rotation == 2){
            scale = -90;
        }

        if(rotation == 3){
            scale = 90;
        }

        if(rotation == 4){
            scale = 180;
        }

        if(rotation == 5){
            scale = 0;
        }
	GL11.glRotatef(scale, 0, 1, 0);
	GL11.glRotatef(90, 0, 1.0F, 0);
}

}

 

Thanks in advance,

you need to incorporate metadata, set each possible rotation to a different metadata value and have the model render the proper rotaton based on the blocks metadata value, which will save when you exit and come back into the game.

[ninjapancakes87]

I did. I set the metadata of the block and i set a byte rotation, which i write to NBT in the tile entity.  I diid some debug code, and the block stays rotated, but the model doesnt.  Also, it reads fine from NBT, but for some reason it doesnt re-render the model when i reload the world.

TEST are rendered every frame

[ninjapancakes87]

Test?

[hydroflame]

TESR*

[ninjapancakes87]

TESR*

Oh yes thats what my tile entity cannon renderer is

[hydroflame]

yeah but what im saying is that TESR are rendered every frame (typicly 60 times per second)

you can see this by printing something during the rendering method

 

can you check that the value is actually messed up in the rendering emthod ?

 

like

 

System.out.println("value of rotation "+cannonTE.getRotation());

*Don't know why I didn't think of that*

For some reason it's not reading right.  It reads the rotation as 0, when originally it was 2.  This weekend I will try having it draw from the metadata.  Did I correctly set the NBT tag in my tile entity?

[ninjapancakes87]

It worked when I used metadata
