I am trying to achieve an effect where every block (lets say crafting table) has a 3x3x3 volume around it marked in red, rendered on top of the environment. I was thinking of drawing all the boxes on a new render layer, then applying that layer after the main game with X% opacity. Issue is, i have no idea how to actually implement this as i am terrible at anything rendering-related
Im on 1.16.1 in case that matters
(artistic rendition of what im trying to achieve attached)

maybe you can render a big block when WorldRenderEvent.Last called(or use mixin)
the code may like" public void render(MatrixStack matrixStack){
RenderListener.saveLocation(this.blockPosition.toLocation());
ResourceLocation identifier = new ResourceLocation("examplemod", "textures/box.png");
ResourceLocation blackIdentifier = new ResourceLocation("examplemod", "textures/black.png");
TextureManager textureManager = Minecraft.getInstance().getTextureManager();
Texture blackTexture=textureManager.getTexture(blackIdentifier);
RenderSystem.disableBlend();
GL20.glEnable(GL20.GL_POLYGON_OFFSET_FILL);
GL20.glPolygonOffset(-1.0f,-1.0f);
Tessellator tessellator = Tessellator.getInstance();
BufferBuilder bufferBuilder = tessellator.getBuilder();
Minecraft.getInstance().getTextureManager().bind(identifier);
bufferBuilder.begin(7, DefaultVertexFormats.POSITION_TEX);
for(BlockFacing normalFacing:BlockFacing.values()){
Location location=getFacingBlockLocation(normalFacing);
boolean hasBlock=RenderListener.hasBlock(location);
if(hasBlock){
continue;
}
vertexBlockFace(matrixStack,normalFacing);
}
tessellator.end();
GL11.glDisable(GL11.GL_POLYGON_OFFSET_FILL);
RenderSystem.enableDepthTest();
RenderSystem.enableBlend();
}"
good luck

Rende...
any suggestions where to look up draw modes?
im currently using 1 to draw wireframes
but here you're using 7
in BufferBuilder#begin
it just seems like magic values

Yes
wait me 3 second
in 1.21,there is a class named "DrawMode",there is the code:" public static enum DrawMode {
LINES(4, 2, 2, false),
LINE_STRIP(5, 2, 1, true),
DEBUG_LINES(1, 2, 2, false),
DEBUG_LINE_STRIP(3, 2, 1, true),
TRIANGLES(4, 3, 3, false),
TRIANGLE_STRIP(5, 3, 1, true),
TRIANGLE_FAN(6, 3, 1, true),
QUADS(4, 4, 4, false);"
maybe the 7 means "QUADS"

alright
thats perfect
pretty much all i needed
im on 1.16.1 though so i guess im sticking to magic values
tysm

you can found more in "watermedia " or "cinemamod",I forget where i found the code
there are similar render function in the mod,when they rendering screen

solved using ```java
RenderSystem.enableBlend();
RenderSystem.blendFunc(GL32.GL_SRC_ALPHA, GL32.GL_ONE_MINUS_SRC_ALPHA);
Tessellator tessellator = Tessellator.getInstance();
BufferBuilder buffer = tessellator.getBuffer();
buffer.begin(DRAW_MODE, VertexFormats.POSITION_COLOR);
for (FaceDir dir : FaceDir.values())
this.addFace(buffer, position, size, dir, color);
tessellator.draw();
RenderSystem.defaultBlendFunc();
RenderSystem.disableBlend();
