Help with drawing lines 1.10.2

[xXWitherBossXx]

Hi everyone! I am just wondering how to draw a line between 2 blocks. I'm making a laser mod, and I want to be able to see the lasers. Also, is there a way to let the block being hit with the laser know that it is being hit with a laser? For example, letting a mirror block know if a laser is hitting it, it's strength, color and size? Any help is very appreciated.

For the "block is hit by a laser" vanilla has no concept of lasers, so you would need to program some kind of interface or capability yourself.

Anything on how to render the lasers? I have no idea and I was looking at some other examples but they just render a line all the time. Also, for the block being hit by laser, I was thinking of using tile entities and sending data between tileentitys. Is this the right approach?

A TileEntity is only needed if you need to store more information than metadata can provide. So no, it isn't.

 

As for rendering, I can offer this:

https://github.com/Draco18s/HarderStuff/blob/master/src/main/java/com/draco18s/hazards/client/HazardsClientEventHandler.java#L371

It's old 1.7 code, but it's updatable as long as you know what you're doing.
