[1.7.10] Redstone only emitted from one side of a block?

[Toastrackenigma]

Hey guys,

I know how to make a block emit a redstone signal by using

public int isProvidingStrongPower(IBlockAccess p_149709_1_, int p_149709_2_, int p_149709_3_, int p_149709_4_, int p_149709_5_) {
        return 15;
}

but that emits a signal from all 6 sides of the block as if it was a redstone block. How do I make it only emit a signal from one side of the block like repeaters do (I have looked through the repeater's code in BlockRedstoneDiode.java and BlockRedstoneRepeater.java and found nothing). There also seems to be nothing online about this topic (no tutorials, etc) or topics asking the same question with no answers.

I believe the last parameter there is the side being checked. 0: down (your block on top, powering the block below), 1: up, etc.

Looking more closely at it in Eclipse so do I, but I don't know how to set it because if I do any of the following it doesn't work:

public int isProvidingStrongPower(IBlockAccess p_149709_1_, int p_149709_2_, int p_149709_3_, int p_149709_4_, int side 2)

public int isProvidingStrongPower(IBlockAccess p_149709_1_, int p_149709_2_, int p_149709_3_, int p_149709_4_, int 2 )

public int isProvidingStrongPower(IBlockAccess p_149709_1_, int p_149709_2_, int p_149709_3_, int p_149709_4_, int side) {
side = 2;
return 15;
}

public int side = 2;
public int isProvidingStrongPower(IBlockAccess p_149709_1_, int p_149709_2_, int p_149709_3_, int p_149709_4_, side)

public int side = 2;
public int isProvidingStrongPower(IBlockAccess p_149709_1_, int p_149709_2_, int p_149709_3_, int p_149709_4_, int side)

etc.

Any tips or am I just making some noobish mistake

I'm taking that my issue is the the latter (i.e. a noobish mistake). To be honest I'm only "fairly decent" with Java (not with programming, I'm great with Javascript, PHP, Python, etc), I've been learning it over the holidays and part of that is making this mod. What have I done wrong?

You last parameter should be an int like "int side".

 

Then you run an if statement checking if thats the side you want and THEN return 15.

 

Eg:

if(side == 3) { //this makes side 3 emit redstone

return 15;

} else {

return 0; }

 

But seriously u need to learn how methods work...

Thanks for telling me that, I thought the params at the top of a method were what I was giving IT, rather than what IT was giving ME (big difference).

Although it worked for my other public boolean canConnectRedstone(IBlockAccess world, int x, int y, int z, int side) method, it didn't work for my actual isProvidingStrongPower block. (While it used to provide power to all 6 sides, it now provides power to none). Here's the code:

public int isProvidingStrongPower(IBlockAccess world, int x, int y, int z, int side) {
    	if (side==3) {
    		return 15;
    	}
    	else {
    		return 0;
    	}
}

You need to also return an int after the else statement

No, you don't.

Technically both are true.  You're just not the one calling the function in this case.
