GL11.glRotated acting weird

[memcallen]

I need some help with this, I'm trying to rotate a jet engine I created (it's a model) with GL11.glRotated but it was acting weirdly

 

heres a link to the video:

 

code for render file:

public class MiniJetEngineRenderer extends TileEntitySpecialRenderer {

public static ModelMiniJetEngine model;

public MiniJetEngineRenderer() {
	this.model=new ModelMiniJetEngine();
}

@Override
public void renderTileEntityAt(TileEntity te, double x, double y, double z, float scale) {

	int x1 = te.xCoord;
	int y1 = te.yCoord;
	int z1 = te.zCoord;
	World world = te.getWorldObj();
	double rotation = 0D;

	if(world.getBlock(x1, y1-1, z1)==gammacraft.Servo){
		RotaryServoTileEntity tile = (RotaryServoTileEntity)world.getTileEntity(x1, y1-1, z1);
		rotation = (double)(tile.Rotation*3.6F);
	}


	GL11.glRotated(rotation, 0D, 1D, 0D);

	GL11.glTranslated(x, y, z);
	this.bindTexture(new ResourceLocation("gammacraft","textures/models/MiniJetEngineBlock.png"));
	this.model.render((Entity)null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);
	GL11.glTranslated(-x, -y, -z);
	GL11.glRotated(-rotation, 0D, 1.0D, 0D);
}

}

 

Also the block below the engine stores it's rotation in radians, which is why I'm multiplying by 3.6F. (I made it like that so you don't have to click 360 times for it to rotate 1 turn)

any GL11 wizards out there know how to fix this?

You first rotate, then translate.

Do it the other way around.

 

Also those are not needed:

	GL11.glTranslated(-x, -y, -z);
	GL11.glRotated(-rotation, 0D, 1.0D, 0D);

 

Instead surround your render code with

GL11.glPushMatrix()

(saves the current matrix state) and

GL11.glPopMatrix()

(restores the previous matrix state, reverting your translation/rotation like you did with your 2 calls).
