I put this into my Gui class method, but I honestly have no idea how GL11 works. however I get an error:

Seems pretty obvious:

You call 2 times GL11.glPopMatrix() without calling any GL11.glPushMatrix() before. Google your error and you'll find help.

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

Fixed it, but now ive come to notice its not rendering the model correctly at all, i see two pixel wide boxes, and thats all:

 

GL11.glPushMatrix();
        GL11.glMatrixMode(GL11.GL_PROJECTION);
        GL11.glPushMatrix();
        GL11.glLoadIdentity();
        ScaledResolution var7 = new ScaledResolution(this.mc.gameSettings, this.mc.displayWidth, this.mc.displayHeight);
        GL11.glViewport((var7.getScaledWidth() - 320) / 2 * var7.scaleFactor, (var7.getScaledHeight() - 240) / 2 * var7.scaleFactor, 320 * var7.scaleFactor, 240 * var7.scaleFactor);
        GL11.glTranslatef(-0.34F, 0.23F, 0.0F);
        GLU.gluPerspective(90.0F, 1.3333334F, 9.0F, 80.0F);
        float var8 = 1.0F;
        GL11.glMatrixMode(GL11.GL_MODELVIEW);
        GL11.glLoadIdentity();
        RenderHelper.enableStandardItemLighting();
        GL11.glTranslatef(0.0F, 3.3F, -16.0F);
        GL11.glScalef(var8, var8, var8);
        float var9 = 5.0F;
        GL11.glScalef(var9, var9, var9);
	this.mc.renderEngine.bindTexture(this.mc.renderEngine.getTexture("/ArcticCraft/mobs/icewolf.png"));
        GL11.glRotatef(20.0F, 1.0F, 0.0F, 0.0F);
        float var10 = this.field_40221_n + (this.field_40224_m - this.field_40221_n) * i;
        GL11.glTranslatef((1.0F - var10) * 0.2F, (1.0F - var10) * 0.1F, (1.0F - var10) * 0.25F);
        float var11 = this.field_40225_j + (this.field_40229_i - this.field_40225_j) * i + 0.15F;
        float var12 = this.field_40225_j + (this.field_40229_i - this.field_40225_j) * i + 0.50F;
        var11 = (var11 - (float)MathHelper.func_40346_b((double)var11)) * 1.6F - 0.3F;
        var12 = (var12 - (float)MathHelper.func_40346_b((double)var12)) * 1.6F - 0.3F;
        GL11.glEnable(GL12.GL_RESCALE_NORMAL);
        huskyModel.render(this.husky, 0.0F, var11, var12, var10, 0.0F, 0.1000F);
        GL11.glDisable(GL12.GL_RESCALE_NORMAL);
        RenderHelper.disableStandardItemLighting();
        GL11.glMatrixMode(GL11.GL_PROJECTION);
        GL11.glViewport(0, 0, this.mc.displayWidth, this.mc.displayHeight);
        GL11.glPopMatrix();
        GL11.glMatrixMode(GL11.GL_MODELVIEW);
        GL11.glPopMatrix();

This is a code snippet from the Turret Book GUI from my Turret Mod, which renders a turret entity and let it rotate automatically:

private int rotateTurret = 0;

private void drawTurret(EntityLiving turret) {
	int xPos = (this.width - this.menuW) / 2;
	int yPos = (this.height - this.menuH) / 2;

	if (turret == null) {
		return;
	}

/* some special code for the turrets, not neccessary
	turret.health = turret.getMaxHealth() / 2;

	if (turret instanceof TurretMod_EntityTurretG) {
		((TurretMod_EntityTurretG) turret).ammo = ((TurretMod_EntityTurretG) turret).maxammo / 2;
	} else if (turret instanceof TurretMod_EntityDefenseBot) {
		((TurretMod_EntityDefenseBot) turret).ammo = ((TurretMod_EntityDefenseBot) turret).maxammo / 2;
		((TurretMod_EntityDefenseBot) turret).isTamed = true;
	}*/

	GL11.glPushMatrix();
	GL11.glColor3f(1F, 1F, 1F);
	GL11.glEnable(32826 /* GL_RESCALE_NORMAL_EXT */);
	GL11.glEnable(2903 /* GL_COLOR_MATERIAL */);
	GL11.glPushMatrix();
	GL11.glTranslatef(xPos + 40, yPos + 98, 50F);
	float f1 = 30F;
	GL11.glScalef(-f1, f1, f1);
	GL11.glRotatef(180F, 0.0F, 0.0F, 1.0F);
	GL11.glRotatef(135F, 0.0F, 1.0F, 0.0F);
	RenderHelper.enableStandardItemLighting();
	GL11.glRotatef(-135F, 0.0F, 1.0F, 0.0F);
	GL11.glRotatef(0.0F, 1.0F, 0.0F, 0.0F);
	turret.renderYawOffset = turret.rotationYaw = turret.prevRotationYaw = turret.prevRotationYawHead = turret.rotationYawHead = this.rotateTurret;
	turret.rotationPitch = 0.0F;
	GL11.glTranslatef(0.0F, turret.yOffset, 0.0F);
	RenderManager.instance.playerViewY = 180F;
	RenderManager.instance.renderEntityWithPosYaw(turret, 0.0D, 0.0D, 0.0D,
			0.0F, 1.0F);
	GL11.glPopMatrix();
	RenderHelper.disableStandardItemLighting();
	GL11.glDisable(32826 /* GL_RESCALE_NORMAL_EXT */);
	GL11.glTranslatef(0F, 0F, 0.0F);
	GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
	GL11.glEnable(32826 /* GL_RESCALE_NORMAL_EXT */);
	int i1 = 240;
	int k1 = 240;
	OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit,
			i1 / 1.0F, k1 / 1.0F);
	GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
	GL11.glDisable(32826 /* GL_RESCALE_NORMAL_EXT */);
	RenderHelper.disableStandardItemLighting();
	GL11.glDisable(2896 /* GL_LIGHTING */);
	GL11.glDisable(2929 /* GL_DEPTH_TEST */);
	GL11.glPopMatrix();
}

 

This method gets called in the drawScreen method of your GUI. Just change the things to your wishes.

 

The rotateTurret integer field gets incremented in the updateScreen method like this.rotateTurret++;

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

And now it also rotates around the head of my actual mob and not only the rendered one in the gui, and the rendered model is kinda dark

 

You should use a new instance of your entity, or else you get these effects. Also menuW and menuH are the width and height of my gui (223 px and 222 px).

private int menuW = 223, menuH = 222;

This is what it looks like:

If its a bit hard to see where it is its at the right of the heal and increase health buttons, the reason its hard to see is because its dark

 

I dunno if there was something changed in the rendering stuff for guis in 1.3. The code is still from the 1.2.5 version of the mod, so I cannot say if it still works correctly for 1.3.

I have to figure this out myself now with an other mod I want to update (which gets a new GUI with features like this). So either you wait until I / an other person respond or you can play with stuff around for yourself.

I think the problem is a colorizing problem. Try to put this code:

GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);

before this line:

RenderManager.instance.renderEntityWithPosYaw(turret, 0.0D, 0.0D, 0.0D,
			0.0F, 1.0F);

Im coding for 1.2.5 just now so it should work then, does it have anything to do with my instance?(the GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F); didnt change anything)

 

public AC_EntityIceWolf huskythingy = new AC_EntityIceWolf(mc.theWorld);

 

Main code:

/**
 * Called from the main game loop to update the screen.
 */
public void updateScreen()
{
	this.rotateWolf++;
	this.rotateWolf++;
}

private void drawWolf(EntityLiving wolf)
{
	if (wolf == null) 
	{
		return;
	}

	int xPos = (this.width) / 2;
	int yPos = (this.height) / 2;

	GL11.glPushMatrix();
	GL11.glColor3f(1F, 1F, 1F);
	GL11.glEnable(32826 /* GL_RESCALE_NORMAL_EXT */);
	GL11.glEnable(2903 /* GL_COLOR_MATERIAL */);
	GL11.glPushMatrix();
	GL11.glTranslatef(xPos + 40, yPos + 98, 50F);
	float f1 = 75F;
	GL11.glScalef(-f1, f1, f1);
	GL11.glRotatef(180F, 0.0F, 0.0F, 1.0F);
	GL11.glRotatef(135F, 0.0F, 1.0F, 0.0F);
	RenderHelper.enableStandardItemLighting();
	GL11.glRotatef(-135F, 0.0F, 1.0F, 0.0F);
	GL11.glRotatef(0.0F, 1.0F, 0.0F, 0.0F);
	wolf.renderYawOffset = wolf.rotationYaw = wolf.prevRotationYaw = wolf.prevRotationYawHead = wolf.rotationYawHead = this.rotateWolf;
	wolf.rotationPitch = 0.0F;
	GL11.glTranslatef(0.0F, wolf.yOffset, 0.0F);
	RenderManager.instance.playerViewY = 180F;
	GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
	RenderManager.instance.renderEntityWithPosYaw(wolf, 0.0D, 0.0D, 0.0D,
			0.0F, 1.0F);
	GL11.glPopMatrix();
	RenderHelper.disableStandardItemLighting();
	GL11.glDisable(32826 /* GL_RESCALE_NORMAL_EXT */);
	GL11.glTranslatef(0F, 0F, 0.0F);

	GL11.glDisable(2896 /* GL_LIGHTING */);
	GL11.glDisable(2929 /* GL_DEPTH_TEST */);
	GL11.glPopMatrix();
}
