[1.7.2]Custom lightsource

[FLUFFY2]

Hello everyone,

I want to modify or create a new light source in the game, but i cant figure out where is minecraft lighting system written. I mean where can i find the .class for it?

I figured out light is not a block in this game its something else.

Thank you for helping!

You mean like a new torch? Use this in the block constructor:

this.setLightLevel(1);

I know how to add light value to a block.

I want to modify the existing light in the game(shape, colour, ect...).

The info is good GreyGhost, but its not what i need.

I want to know where should i look around in the minecraft source.

If its created with OpenGL where is the OpenGl class that creates the actual light?

Thanks!

That's tricky because you need to to change the whole lighting engine with ASM to do that.

Do you mean you want to create a light source which illuminates the surrounding blocks with (say) red light instead of the yellow light from a torch?

 

Or do you mean you want a torch which looks red, but still lights up the surrounding blocks with yellow light?

Hi

 

Changing the lighting model in Minecraft will be very difficult, because it does not work like you think it does.  See the link(s) I posted earlier.

You can change the colour of the block light in the light map to make it more orange, that will affect every torch and glowstone in the game.  And even that is rather difficult.

 

I would suggest to forget about it and try something easier

So you guys have no idea where the light engine is written.

Good places to start are

RenderBlocks.renderStandardBlock

RenderHelper for item lighting

OpenGlHelper

EntityRenderer.enableLightMap

and

EntityRenderer.renderWorld
