[1.7.10] Tesselator/TESR rendering .png black

[Xcox123]

Hey, I was making a custom rendered block with Tesselators for the first time, and when I saw my block the place where my .png was supposed to be placed was black(my png is bright pink). Can anyone help? Heres my rendering code:

 

public class TileEntityRenderWindmill extends TileEntitySpecialRenderer {
private final ResourceLocation textureWindmill = new ResourceLocation("tehfoodmod", "textures/model/windmill.png");

private int textureWidth = 64;
private int textureHeight = 32;

    @Override
    public void renderTileEntityAt(TileEntity tileentity, double x, double y, double z, float f) {
    	GL11.glPushMatrix();
    	GL11.glTranslatef((float)x, (float)y, (float)z);
    	
    	
    	Tessellator tess = Tessellator.instance;
    	this.bindTexture(textureWindmill);
    	tess.startDrawingQuads(); //Starts drawing
    	{
    		tess.addVertexWithUV(0, 0, 1, 1, 1);
    		tess.addVertexWithUV(1, 1, 1, 1, 0);
    		tess.addVertexWithUV(0, 1, 0, 0, 0);
    		tess.addVertexWithUV(0, 0, 0, 0, 1);
    	}
    	tess.draw(); //Draws
    	GL11.glPopMatrix();
    }
}

Hi

 

You still need to set the colour and the lighting before rendering.  For example

 

        tessellator.setColorOpaque_F(1, 1, 1);

        //This will make your block brightness dependent from surroundings lighting.
        int brightness = block.getMixedBrightnessForBlock(world, x, y, z);
        tessellator.setBrightness(brightness);

Awesome thanks! One question though(prob nooby), where do I get my IBlockAccess from in a TESR?

[TheGreyGhost]

World implements IBlockAccess so just use world.

Nope, still black, heres my code now

public void renderTileEntityAt(TileEntity tileentity, double x, double y, double z, float f) {
    	GL11.glPushMatrix();
    	GL11.glTranslatef((float)x, (float)y, (float)z);
    	
    	Tessellator tess = Tessellator.instance;
    	this.bindTexture(textureWindmill);
    	IBlockAccess world = tileentity.getWorldObj();
    	int brightness = tehfoodmod.blockWindmill.getMixedBrightnessForBlock(world, tileentity.xCoord, tileentity.yCoord, tileentity.zCoord);

	tess.setBrightness(brightness);
	tess.setColorOpaque_F(1.0F, 1.0F, 1.0F);
    
    	tess.startDrawingQuads(); //Starts drawing
    	{
    		tess.addVertexWithUV(0, 0, 1, 1, 1);
    		tess.addVertexWithUV(1, 1, 1, 1, 0);
    		tess.addVertexWithUV(0, 1, 0, 0, 0);
    		tess.addVertexWithUV(0, 0, 0, 0, 1);
    	}
    	tess.draw(); //Draws
    	GL11.glPopMatrix();
    }

[TheGreyGhost]

You need to do the startDrawingQuads before the setBrightness and setColorOpaque, not after.

I did that ^^ and still no differance.

[Zetal]

Double-check that you have a texture located in (yourrootfolder)/src/main/resources/assets/textures/model/windmill.png

[Xcox123]

Yup it's there. It's loading a texture, just its rendering black(no purple)

[Zetal]

I had an entity rendering just black earlier the other day, I believe it was because the block had the correct texture, but the entity did not. Of course, mine still isn't working properly... (it's all solid red, now...) so I guess I'm not in a position to give out help advice.

[Xcox123]

anyone else got a solution?

[TheGreyGhost]

Hi

 

That code should work (I have done something identical not long ago) - pls show your latest renderer code, also a screenshot of what the black block looks like and what your texture bitmap image looks like?

Just saying, ^^ is found at this path: C:\Users\Adam\Desktop\Modding\1.7\TehFoodMod\Source\src\main\resources\assets\tehfoodmod\textures\model

Hi

 

Have you tried this order?

 

    @Override
    public void renderTileEntityAt(TileEntity tileentity, double x, double y, double z, float f) {
    	GL11.glPushMatrix();
    	GL11.glTranslatef((float)x, (float)y, (float)z);
    	
    	Tessellator tess = Tessellator.instance;
    	this.bindTexture(textureWindmill);
    	IBlockAccess world = tileentity.getWorldObj();
    	
    
    	tess.startDrawingQuads(); //Starts drawing

    	int brightness = tehfoodmod.blockWindmill.getMixedBrightnessForBlock(world, tileentity.xCoord, tileentity.yCoord, tileentity.zCoord);
tess.setBrightness(brightness);
tess.setColorOpaque_F(1.0F, 1.0F, 1.0F);

    	{
    		tess.addVertexWithUV(0, 0, 1, 1, 1);
    		tess.addVertexWithUV(1, 1, 1, 1, 0);
    		tess.addVertexWithUV(0, 1, 0, 0, 0);
    		tess.addVertexWithUV(0, 0, 0, 0, 1);
    	}
    	
    	tess.draw(); //Draws

    	GL11.glPopMatrix();
    	
    }

 

Also, do you mean for it to have that twisted appearance?  Normally the four points of the Quad are supposed to lie in the same plane, but yours is bent.

[Xcox123]

Yeah, I was only half way through testing when I noticed the texture issue so the quads are all messed up

 

And still nothing. I'm about to github the whole mod, so maybe something's up there? https://github.com/Xcox123/TehFoodMod

 

 

[TheGreyGhost]

 

Well I tried your code and the problem was that you spelled BlockWindmill.isOpaqueCube() with a Q instead of an O, i.e. isQpaqueCube().  So the getMixedBrightness always always returned 0.

 

If you put @Override before methods like this it will help pick up these problems.

    @Override
    public boolean isOpaqueCube(){
        return false;
    }

 

I also added  RenderHelper.disableStandardItemLighting(); just in case it has been left in that mode (which might cause random-looking brightness variations)

 

If you want your block to be full brightness all the time, you can just use

final int FULL_SKY_BRIGHTNESS = 255;
tess.setBrightness(FULL_SKY_BRIGHTNESS);

 

    @Override
    public void renderTileEntityAt(TileEntity tileentity, double x, double y, double z, float f) {
    	GL11.glPushMatrix();
    	GL11.glTranslatef((float)x, (float)y, (float)z);
    	
    	Tessellator tess = Tessellator.instance;
    	this.bindTexture(textureWindmill);
    	IBlockAccess world = tileentity.getWorldObj();
        RenderHelper.disableStandardItemLighting();   // turn off item lighting
    
    	tess.startDrawingQuads(); //Starts drawing

    	int brightness = tehfoodmod.blockWindmill.getMixedBrightnessForBlock(world, tileentity.xCoord, tileentity.yCoord, tileentity.zCoord);
tess.setBrightness(brightness);
tess.setColorOpaque_F(1.0F, 1.0F, 1.0F);

    	{
    		tess.addVertexWithUV(0, 0, 1, 1, 1);
    		tess.addVertexWithUV(1, 1, 1, 1, 0);
    		tess.addVertexWithUV(0, 1, 0, 0, 0);
    		tess.addVertexWithUV(0, 0, 0, 0, 1);
    	}
    	
    	tess.draw(); //Draws

    	GL11.glPopMatrix();
    	
    }

Oh my god I am so stupid It works now thanks for helping me!

No worries, glad we solved it. 

 

Although it seems to have earned me a smite along the way for some reason
