[Question / Feature Request] Autoscaling.

[CrossVas]

Hey,

I'm having a great time exploring BlockHelper mod and adding new features through my addon.
However, there is one issue that stands out the most - scaling.

Use case:
Using MC Auto scale:

Using MC Large scale:

While for my setup the Large scale works just fine (on a QHD resolution), for FHD and lower this might be a problem:

FHD instance:

I know there is a way to change the scaling using BlockHelper - Aspect menu, but it would be great to have autoscaling also.
Or, if possible, is there a way I can dynamically change the scale using my IDataProvider#modifyBody

Thanks!

Hey again! :)
That's great to hear!

Yes, you can set the OverlayConfig.scale variable in code, for example:
https://github.com/ThexXTURBOXx/BlockHelper/blob/1.5.2/src/main/java/mcp/mobius/waila/gui/screens/config/ScreenHUDConfig.java#L273-L274
But... It would indeed be better to provide a way to more easily (and reliably) set this value.
Do you think it would be helpful to have another event WailaRenderEvent.PreScale, which allows one to set the scaling value? Right before this line?:
https://github.com/ThexXTURBOXx/BlockHelper/blob/1.5.2/src/main/java/mcp/mobius/waila/overlay/OverlayRenderer.java#L52

I’d like to suggest an alternative to adding a WailaRenderEvent.PreScale.
Instead of exposing another event just to change the scale, how about applying a built-in auto-scaling mechanism directly in the overlay renderer?

For example, this logic could be inserted right before GL11.glScalef(...) in OverlayRenderer:
(untested pseudo code)

	// Base scale from config
	float scale = OverlayConfig.scale;

	// Screen size
	ScaledResolution res = new ScaledResolution(Minecraft.getMinecraft().gameSettings, Minecraft.getMinecraft().displayWidth, Minecraft.getMinecraft().displayHeight);
	float screenHeight = res.getScaledHeight();

	// Threshold: percentage of screen height allowed for the overlay (0.4 or 0.5)
	float thresholdHeight = screenHeight * 0.4f; // Make it configurable

	// Get the overlay height
	float overlayHeight = tooltip.pos.getHeight(); // Or wherever tooltip height is stored

	// Auto-scale if necessary
	if (overlayHeight * scale > thresholdHeight) {
		scale = Math.max(scale * 0.5f, thresholdHeight / overlayHeight);
	}

	// Apply scale
	GL11.glScalef(scale, scale, 1.0f);
