How do I render bounding box to entity?


Recommended Posts

I want the bounding box to be visible to the entity the player is looking at. But the bounding box is displayed to me.

How do I display this to entity?

 

This is my code:

 

@SubscribeEvent
    public void renderWorldLastEvent(RenderWorldLastEvent event) {

        if (Minecraft.getMinecraft().objectMouseOver.entityHit != null) {
            renderEntityBox(Minecraft.getMinecraft().objectMouseOver.entityHit, event.getPartialTicks());
        }
    }

    void renderEntityBox(Entity entity, float PartialTicks) {

        AxisAlignedBB boundingBox = entity.getEntityBoundingBox();

        double d0 = entity.lastTickPosX + (entity.posX - entity.lastTickPosX) * (double)PartialTicks;
        double d1 = entity.lastTickPosY + (entity.posY - entity.lastTickPosY) * (double)PartialTicks;
        double d2 = entity.lastTickPosZ + (entity.posZ - entity.lastTickPosZ) * (double)PartialTicks;
        Tessellator.getInstance().getBuffer().setTranslation(-d0, -d1, -d2);
        RenderGlobal.drawSelectionBoundingBox(boundingBox, 1.0F,1.0F,1.0F,1.0F);
        Tessellator.getInstance().getBuffer().setTranslation(0,0,0);
    }

Or can the entity's outline be displayed in red? Instead of doing it like a Glowing effect, it's red.

This is because opengl coordinate space defines the coordinate (x0, y0, z0) as the camera position. In order to have the bounding box displayed around the entity, you would have to translate (and probably also rotate) the bounding box to the entity position.

 

You could check out the code used in minecraft debug mode (Pressing F3+B).

first translate to world origin 0,0,0

GlStateManager.translate(-player.posX, -player.posY, -player.posZ);

 

then translate to the entity position

GlStateManager.translate(entity.posX, entity.posY, entity.posZ);

 

 

 

but you should combine them to one translate call, like

GlStateManager.translate(entity.posX - player.posX, entity.posY - player.posY, entity.posZ - player.posZ);

    • I may have simply needed to update the import. Sorry about that.
    • I'm using forge-1.17.1-37.0.15-mdk, and the empty project starts without any problems. I have no idea where the problem lies.
    • It happens with Language Support for Java. Because of this error, my code will not be able to resolve the reference. Please help me.

    • Can someone please tell me why this is happening and help me find a solution. thanks. Edit: Nevermind I figured it out.
    • I am trying to store data through my ItemStack capability storage, but I stumbled upon a roadblock. My ItemStack Capability Storage: public class WandItemStorage implements Capability.IStorage<IWandCap> { @Nullable @Override public INBT writeNBT(Capability<IWandCap> capability, IWandCap instance, Direction side) { CompoundNBT tag = new CompoundNBT(); tag.put("spells", instance.getSpells()); return tag; } @Override public void readNBT(Capability<IWandCap> capability, IWandCap instance, Direction side, INBT nbt) { } } My ItemStack Capability: public class WandCap implements IWandCap { private List<Spell> spells; public WandCap () { spells = new ArrayList<>(); } @Override public List<Spell> getSpells() { return this.spells; } @Override public void addSpells(Spell... spells) { this.spells.addAll(Arrays.asList(spells)); } @Override public void addSpell(Spell spell) { this.spells.add(spell); } @Override public void removeSpells(Spell... spells) { this.spells.removeAll(Arrays.asList(spells)); } @Override public void removeSpell(Spell spell) { this.spells.remove(spell); } @Override public boolean containsSpell(Spell spell) { return this.spells.contains(spell); } } I'm currently trying to put a List of Spells (my custom object) to the Write and Read NBT methods of my ItemStack cap storage, but CompoundNBT doesn't have a method for putting a custom object into a tag. All it has is the put() method from what I'm seeing, however the put() method requires an INBT for the second parameter, which I do not have. Would I need to convert my List of Spells to an INBT, and how would I go about doing that?
