Hey everyone,

 

I am trying to render a block onto a GUI in 3D. I'm not using the ItemRenderer code, because the block has to be in full 3D. I am trying to render it, but it isn't working. It's not crashing the game or throwing errors, but it isn't rendering all the same. I need to work this out to finish the mod.

 

Here's the render code:

public void renderModel() {

	RenderBlocks blockRenderer = new RenderBlocks(Minecraft.getMinecraft().theWorld);
	Minecraft.getMinecraft().renderEngine.bindTexture(TextureMap.locationBlocksTexture);

	for(BlockData data : getBlocks()) {

		GL11.glPushMatrix();
		GL11.glScalef(data.getScaleX(), data.getScaleY(), data.getScaleZ());
		GL11.glTranslatef(data.getPositionX(), data.getPositionY(), data.getPositionZ());
        blockRenderer.renderBlockAllFaces(data.getBlock(), 0, 0, 0);
		GL11.glPopMatrix();

	}

}

 

Here's the GUI code:

package assets.blockmodeller.client.gui;

import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.FontRenderer;
import net.minecraft.client.gui.Gui;
import net.minecraft.client.gui.GuiScreen;
import net.minecraft.client.renderer.OpenGlHelper;
import net.minecraft.client.renderer.RenderHelper;
import net.minecraft.client.resources.I18n;
import net.minecraft.init.Blocks;
import net.minecraft.item.ItemStack;
import net.minecraft.network.play.client.C01PacketChatMessage;

import org.lwjgl.opengl.GL11;
import org.lwjgl.opengl.GL12;

import assets.blockmodeller.client.model.BlockData;
import assets.blockmodeller.client.model.Model;

public class GuiBlockModeller extends GuiScreen {

public Model model;

public GuiBlockModeller() {

	model = new Model("New Model");
	model.addBlock(Blocks.grass, 0);

}

public void initGui() {

	Minecraft.getMinecraft().thePlayer.sendQueue.addToSendQueue(new C01PacketChatMessage("/me " + I18n.format("mutliplayer.blockmodeller.guiOpened")));

}

public void drawScreen(int mx, int my, float f) {

	drawDefaultBackground();
	super.drawScreen(mx, my, f);
	renderModel(51, 75);

}

public void renderModel(int x, int y) {

	GL11.glEnable(GL11.GL_COLOR_MATERIAL);
	GL11.glPushMatrix();
	GL11.glTranslatef((float)x, (float)y, 50.0F);
	//GL11.glRotatef(180.0F, 0.0F, 0.0F, 1.0F);
	model.renderModel();
	GL11.glPopMatrix();
	RenderHelper.disableStandardItemLighting();
	GL11.glDisable(GL12.GL_RESCALE_NORMAL);
	OpenGlHelper.setActiveTexture(OpenGlHelper.lightmapTexUnit);
	GL11.glDisable(GL11.GL_TEXTURE_2D);
	OpenGlHelper.setActiveTexture(OpenGlHelper.defaultTexUnit);
	this.mc.renderEngine.bindTexture(Gui.icons);

}

private void drawItemStack(ItemStack p_146982_1_, int p_146982_2_, int p_146982_3_, String p_146982_4_) {

        GL11.glTranslatef(0.0F, 0.0F, 32.0F);
        this.zLevel = 200.0F;
        itemRender.zLevel = 200.0F;
        FontRenderer font = null;
        if (p_146982_1_ != null) font = p_146982_1_.getItem().getFontRenderer(p_146982_1_);
        if (font == null) font = fontRendererObj;
        itemRender.renderItemAndEffectIntoGUI(font, this.mc.getTextureManager(), p_146982_1_, p_146982_2_, p_146982_3_);
        itemRender.renderItemOverlayIntoGUI(font, this.mc.getTextureManager(), p_146982_1_, p_146982_2_, p_146982_3_, p_146982_4_);
        this.zLevel = 0.0F;
        itemRender.zLevel = 0.0F;
    
}

public boolean doesGuiPauseGame() {

	return false;

}

}

 

Can anyone help? It would really help me out, and please, not ItemRenderer!

What are the symptoms?

 

I'd suggest you use the vanilla rendering code for inspiration, eg RenderBlocks.renderBlockAsItem()

I just want to be able to render a full 3D block on my GUI. I would prefer to use RenderBlocks instead of RenderItem.

The code looks fine at first glance, maybe trying to retro fit the IItemRenderer code to work with your GUI this way you use MC pipeline for rendering objects.

 

To better clarify that I am understanding what your are doing, you are trying to render a normal 3D object on the screen to preview it. Correct?

 

 

Maybe you can use

RenderBlocks#renderBlockAsItem(block,metadata,1F)

?
