[1.8] Render not taking into account the world lighting.

[Jedispencer21]

What I wondering is how does vanilla render things such as a player name/entity name tag above the entity and get it to take into account the world lighting, I have setup a sort of text render that renders above the horse to tell its stats but the text does not take into account the lighitng.

This is what it looks like:

 

This is the code:

 

 

        // Renders the text above the entity

public static void renderText(String[] text, float x, float y, float z, int color, boolean renderBlackBG, float partialTickTime)

{

float playerX = (float) (mc.thePlayer.lastTickPosX + (mc.thePlayer.posX - mc.thePlayer.lastTickPosX) * partialTickTime);

float playerY = (float) (mc.thePlayer.lastTickPosY + (mc.thePlayer.posY - mc.thePlayer.lastTickPosY) * partialTickTime);

float playerZ = (float) (mc.thePlayer.lastTickPosZ + (mc.thePlayer.posZ - mc.thePlayer.lastTickPosZ) * partialTickTime);

float dx = x - playerX;

float dy = y - playerY;

float dz = z - playerZ;

float distance = (float) Math.sqrt(dx * dx + dy * dy + dz * dz);

FontRenderer fontrenderer = mc.getRenderManager().getFontRenderer();

float f = 1.6F;

float f1 = 0.016666668F * f;

 

GlStateManager.pushMatrix();

GlStateManager.translate(dx, dy, dz);

GL11.glNormal3f(0.0F, 1.0F, 0.0F);

setupRendering(-f1, -f1, -f1);

Tessellator tessellator = Tessellator.getInstance();

WorldRenderer worldrenderer = tessellator.getWorldRenderer();

GlStateManager.disableDepth();

int textWidth = 0;

 

for (String message : text)

{

int messageWidth = fontrenderer.getStringWidth(message);

if (messageWidth > textWidth) textWidth = messageWidth;

}

 

int lineHeight = 10;

 

if (renderBlackBG)

{

GlStateManager.disableTexture2D();

worldrenderer.startDrawingQuads();

int j = textWidth / 2;

worldrenderer.setColorRGBA_F(0.0F, 0.0F, 0.0F, 0.5F);

worldrenderer.addVertex((double) (-j - 1), (double) (-1 + 0), 0.0D);

worldrenderer.addVertex((double) (-j - 1), (double) (8 + lineHeight * text.length - lineHeight), 0.0D);

worldrenderer.addVertex((double) (j + 1), (double) (8 + lineHeight * text.length - lineHeight), 0.0D);

worldrenderer.addVertex((double) (j + 1), (double) (-1 + 0), 0.0D);

tessellator.draw();

GlStateManager.enableTexture2D();

}

 

int i = 0;

 

for (String message : text)

{

GlStateManager.disableDepth();

fontrenderer.drawString(message, -textWidth / 2, i * lineHeight, 553648127);

GlStateManager.enableDepth();

fontrenderer.drawString(message, -textWidth / 2, i * lineHeight, color);

++i;

}

 

GlStateManager.enableLighting();

GlStateManager.depthMask(true);

GlStateManager.disableBlend();

GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);

GlStateManager.popMatrix();

}

 

        // Renders the item above the entity

public static void renderItemIcon(float x, float y, float z, Item item, float partialTickTime)

{

RenderManager rendermanager = mc.getRenderManager();

float playerX = (float) (mc.thePlayer.lastTickPosX + (mc.thePlayer.posX - mc.thePlayer.lastTickPosX) * partialTickTime);

float playerY = (float) (mc.thePlayer.lastTickPosY + (mc.thePlayer.posY - mc.thePlayer.lastTickPosY) * partialTickTime);

float playerZ = (float) (mc.thePlayer.lastTickPosZ + (mc.thePlayer.posZ - mc.thePlayer.lastTickPosZ) * partialTickTime);

float dx = x - playerX;

float dy = y - playerY;

float dz = z - playerZ;

float scale = 0.025F;

 

GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);

GlStateManager.pushMatrix();

GlStateManager.translate(dx, dy, dz);

rotateByView(mc.getRenderManager());

GlStateManager.scale(-scale, -scale, -scale);

GlStateManager.disableLighting();

if (AnimalInformation.showThroughBlocks) GlStateManager.disableDepth();

GlStateManager.enableBlend();

GlStateManager.blendFunc(770, 771);

GlStateManager.disableDepth();

GlStateManager.color(0.5F, 0.5F, 0.5F, 1.0F);

renderItemTexture(-8, -8, item, 16, 16);

GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);

GlStateManager.enableDepth();

renderItemTexture(-8, -8, item, 16, 16);

GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);

if (AnimalInformation.showThroughBlocks) GlStateManager.enableDepth();

GlStateManager.enableLighting();

GlStateManager.popMatrix();

}

 

        // Rotates the object based on the viewpoint

private static void rotateByView(RenderManager rendermanager)

{

GlStateManager.rotate(-rendermanager.playerViewY, 0.0F, 1.0F, 0.0F);

GlStateManager.rotate(Minecraft.getMinecraft().gameSettings.thirdPersonView != 2 ? rendermanager.playerViewX : -rendermanager.playerViewX, 1.0F, 0.0F, 0.0F);

}

 

        // Sets up the basic rendering

public static void setupRendering(float scaleX, float scaleY, float scaleZ)

{

rotateByView(mc.getRenderManager());

GlStateManager.scale(scaleX, scaleY, scaleZ);

GlStateManager.disableLighting();

GlStateManager.depthMask(false);

GlStateManager.disableDepth();

GlStateManager.enableBlend();

GlStateManager.tryBlendFuncSeparate(770, 771, 1, 0);

}

No one?

Do GL11.glDisable(GL11.GL_LIGHTING) and enable it after your rendering code has passed.

[Jedispencer21]

I already do disable and enable the lighting, it gets disabled in the setupRendering method, and enabled after the render is done at the end of the methods.

[Draco18s]

Random guess:

 

Have you tried

GL11.glDisable(GL11.GL_TEXTURE_2D);

?

 

I was doing some GL work a few weeks back and not having that disabled was causing what looked like lighting glitches.

[Jedispencer21]

I disable it when I draw the background but not when drawing the text.

Hi

 

You might get some useful clues from this code for rendering a TESR, if you want to turn world lighting on.

https://github.com/TheGreyGhost/MinecraftByExample/blob/master/src/main/java/minecraftbyexample/mbe21_tileentityspecialrenderer/TileEntitySpecialRendererMBE21.java

 

OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, SKY_LIGHT_VALUE * 16.0F, BLOCK_LIGHT_VALUE * 16.0F);

 

Alternatively, depending on the event you're using for your rendering, the EntityFX rendering might also have stuff of interest

Entity.getBrightnessForRender()  - in particular see

EffectRenderer.renderLitParticles()

and

EffectRenderer.renderParticles()

 

-TGG

 

[Jedispencer21]

So I have searched around for the setLightmapTextureCoords and the most common use is using Entity#getBrightnessForRender but when I apply that to my render, nothing changes, I also syso the value of the getBrightnessForRender, but that never changes either.
