[1.12.2] Minimap-like floating text that enlarges

[San3001]

I'd like to create some floating text like this(see attachment) minimap mod JourneyMap, though I have no idea where to start.

Would be appreciated if someone could guide me to some steps I'd need to do

 

I know how to make floating text the armorstand client side way but that doesn't increase size

You could try to use the same logic EntityRenderer.drawNameplate has(or maybe even straight up use that method) but scale the drawn textbox with distance to the player.

How does EntityRenderer.drawNameplate work? Do I just input coordinates and text displays there? Can't get it working.

Like, do I put it in a Tick Event? or

Well you obviously need to call it from some kind of event that gets called every frame. RenderWorldLast or RenderTickEvent for example.

 

As for the arguments passed see what Render#renderLivingLabel does.

This doesn't seem to work

 

public RenderManager renderManager = mc.getRenderManager();
	
	@SubscribeEvent
	public void renderTick(TickEvent.RenderTickEvent event) {
		EntityPlayerSP player = mc.player;
		
		EntityRenderer.drawNameplate(renderManager.getFontRenderer(), "text", 0f, 64f, 0f, 0, player.cameraYaw, player.cameraPitch, renderManager.options.thirdPersonView == 2, player.isSneaking());
	
	}

 

Did I mess something up?

Thanks for your help

How are you registering your event subscriber?

when is this initialized? It could be null.

This has two phases - you need to check the phase first before doing anything.

This could be null when RenderTickEvent fires.

These are your x,y,z coordinates. Are you sure you want it to be drawn at 0, 64, 0?

 

If you are not crashing then your event handler isn't registered. Otherwise fix what I told you to fix.

Doing it in postInit

Yeah, it was crashing before but I just made a command to change a run boolean I had.

I just wanted it to work to start somewhere.

Right now I just want it to spawn in a static position(0, 64, 0) . I'll change it later

 

I don't know where else to get player or render manager so.. would this work?

renderManager never returns null for some reason, but renderManager.getFontRenderer() does

 

public RenderManager renderManager = mc.getRenderManager();
	
	@SubscribeEvent
	public void renderTick(TickEvent.RenderTickEvent event) {
		if (event.phase == TickEvent.Phase.START || renderManager.getFontRenderer() == null || mc.player == null) {
			return;
		}
		EntityPlayerSP player = mc.player;
		EntityRenderer.drawNameplate(renderManager.getFontRenderer(), "text", 0f, 64f, 0f, 0, player.cameraYaw, player.cameraPitch, renderManager.options.thirdPersonView == 2, player.isSneaking());
	
	}

It doesn't crash anymore but it also still doesn't work.

I feel this is a really lazy way to do this.

Don’t get the player, get the current view entity

private Minecraft mc = Minecraft.getMinecraft();

		if (event.phase == TickEvent.Phase.START || renderManager.getFontRenderer() == null) {

		Entity viewEntity = mc.getRenderViewEntity();
		EntityRenderer.drawNameplate(renderManager.getFontRenderer(), "text", 0f, 64f, 0f, 0, viewEntity.rotationYaw, viewEntity.rotationPitch, renderManager.options.thirdPersonView == 2, viewEntity.isSneaking());
	
	}

Like this? Still can't see but it looks like better code

I did some debugging with your code and here are the results:

TickEvent.RenderTickEvent

Turns out this is not the right event to render things in the world because the GL matrices aren't correct. RenderWorldLast works just fine though.

0f, 64f, 0f

These 3 parameters are the x,y,z relative to the camera's position, not relative to 0,0,0 in the world. So kept like this they will make the text render 64 blocks directly above the camera. So to render at 0, 64, 0 you would need to translate against the camera first by subtracting the camera's position from these coordinates.

viewEntity.rotationYaw, viewEntity.rotationPitch

These parameters don't want the yaw and pitch, they want the RenderManager.playerViewY and RenderManager.playerViewX instead.

Use Minecraft.fontRenderer instead.

 

After I've applied all these fixes the nameplate did indeed render in the world.

public void renderTick(RenderWorldLastEvent event) {
	if (fontRenderer == null || mc.player == null || renderManager == null || renderManager.options == null) {
		return;
	}

		
	EntityPlayerSP player = mc.player;
	EntityRenderer.drawNameplate(fontRenderer, "text", 2f, 0f, 0f, 0, renderManager.playerViewY, renderManager.playerViewX, renderManager.options.thirdPersonView == 2, player.isSneaking());
	
}

This works perfectly, thank you so much! Subtracting player position should be easy enough.
