I want to port a mod to forge and I'm getting help from an experienced modder but neither of us have any clue as to how to add overlays to blocks. The mod I'm trying to port over is found on a minecraft forum page and you can get to it by googling "easy redstone mod". Please help

How do you use it

 

Did you have a look at the easy redstone mod I directed you to as then you'll see what I'm talking about with my question. I want to add overlays to blocks when they reach a certain

criteria

 

What does RenderWorldLastEvent do

 

So how will that help with overlays of blocks

 

So how would I be able to render ontop of blocks using RenderWorldLastEvent

The important question that I've always ased myself is: When this event has been called, how do I find out, which chunk just got redrawn? It wouldn't make much sense to redraw the whole world.

Makes it pretty useless for block overlays, you would get an enormous amount of lag if you redraw the overlay for several blocks every render tick...

Probably a coremod would be useful here, or is there a chance that forge adds events when chunks are rendered?

This doesn't use a core mod. Maybe finding out how they render the paint will help with overlays

 

Sorry to say that youre wrong. This mod does use a coremod included in the jar file.

Is this overlay for the block that the player is looking at? In that case I think maybe the DrawBlockHighlightEvent is better to use.

 

You might actually be able to use the DrawBlockHighlightEvent to overlay other blocks in the local area as well.
