Redstone Help

[AF777]

So I want to make a block emit light when a redstone signal is applied to it. I know how to make it emit light but I don't know how to make it detect the redstone signal.

 

	myFirstBlock = new BlockFirst(538,0);
	myFirstBlock.setLightValue(1F);
	LanguageRegistry.addName(myFirstBlock, "My first block");
	MinecraftForge.setBlockHarvestLevel(myFirstBlock,"pickaxe",0);
	GameRegistry.registerBlock(myFirstBlock);

 

That's the piece of code that creates the block. This is written just after the '@Init' in the Base Mod file. I have defined myFirstBlock after the '@SidedProxy' further up in the code.

 

The block creation works fine.

 

Could I please just get some help with the redstone signal detection?

 

 

 

Thanks

I suggest you have a look at vanilla redstone lamps.

 

Pretty much this.

You'll need two blocks for it to work, as how much light a block emits doesn't update based on state (or rather, it's very very difficult to get it to do so).

You can do it with metadata no problem actually.

I second this. Just because MC uses multiple IDs for something does not mean that is the only way to do it; frankly, Mojang is rather lazy when it comes to metadata use.

And they are perfectly fine to do so.

Mods "abuse" metadata to save on block ids, but thats not what metadata is intended for. Mojang is the creator of the game after all, so they don't have to worry about stuff like running out of block ids.

What is it intended for? Also, they would have to (eventually) worry about running out of IDs - the limit is a technical one (the limit of a byte), so it is not like they could change it (without severe consequences for world file size and performance) if they ever ran to 255 blocks.

And even if they do run out of those 4096 block ids they are free to change it to 2 full bytes whenever they want to. Its their game after all.

Free in the sense that they are permitted to do so. Not in the sense that the game would get away with it without suffering from it.

The problem was not that "can you make multiple states without using more block IDs" but rather getting the light illumination level based on metadata.

 

Doable, but it wasn't strait forward.

 

See this thread for a working example.

Ah, Ok.

 

Thanks for the help.

 

Metadata is like the special ID that the block gets, right? Like: 143:1 (Example)

 

If it is then I'll just have to wait for a metadata tutorial.

[AF777]

Oh, and, how would I get to viewing the code for Redstone Lamps?

[Mew]

it would be in the blocks package in minecraft source code

 

I hope you realise that seems a really dumb and noobish question... I am pretty sure you are not a noob
