[1.7.2] How to check if player is in creative mode

[Electrobob99]

Basically I want to know how I could check whether a player is in creative or not and use it within an if statement. Mainly need this because one of my blocks drops it's drop in creative upon being broken.

[Zer0HD2]

Check player.capabilities.isCreativeMode.

[Electrobob99]

Check player.capabilities.isCreativeMode.

Hmm.. Guessing you mean PlayerCapabilities.isCreativeMode... But how so. Because I know it would never work in an if statement due to certain reasons.

[Zer0HD2]

No, I mean an instance of EntityPlayer called player. player.capabilities.isCreativeMode returns a boolean value of true is the player is in creative. Take a look at the wolf interact method if you want to see an example of it being used in an if statement.

-statement due to reasons?

I basically say this for this instance because it keeps saying: "Cannot make a static reference to the non-static field" anytime I try

And this is the method where I'm trying to work it in:

 

public void breakBlock(World world, int x, int y, int z, Block block, int meta)
{


	switch(meta){
	case 0:
		world.setBlockToAir(x,y,z);			
		break;
	case 1:	
		world.setBlock(x, y, z, Blocks.clay, 0, 1);

		block.dropBlockAsItem(world, x, y+1, z, 1, 1);
		break;
	case 2:	
		world.setBlock(x, y, z, Blocks.dirt, 0, 1);
		break;
	case 3:	
		world.setBlock(x, y, z, Blocks.sand, 0, 1);
		break;
	default:
		break;
	}

}

As Zer0HD2 put, you'll want an instance of

EntityPlayer

.

 

Fetch the

capabilities

field of this instance.

 

Fetch the

isCreativeMode

field from the

capabilities

field.

Ok how do I do that exactly. Do I make a new PlayerCapabilities at the top like this to start it off:

public PlayerCapabilities capabilities = new PlayerCapabilities();

 

I just don't understand what is meant by fetch, i'm probably over thinking it *facepalm

[Elyon]

For the current client:

 

Minecraft.getMinecraft().thePlayer.capabilities.isCreativeMode

 

fetch#Verb

[Electrobob99]

For the current client:

 

Minecraft.getMinecraft().thePlayer.capabilities.isCreativeMode

 

fetch#Verb

Ok, how was I supposed to know to get that? and I'm guessing I'm not supposed to put it in the if statement, because it doesn't seem to be working

This is just Ironic, I get 98s in advanced java coding courses in college, and yet this makes no sense.

[Zer0HD2]

isCreativeMode returns a boolean, so it should work in an if statement. I've used it like that before.

 

As long as you have an instance of EntityPlayer, you can use this field. As Elyon said, Minecraft.getMinecraft().thePlayer returns the client player, in the form of an EntityPlayer.

Hmm, then why doesn't this not seem to work?:

 

public void breakBlock(World world, int x, int y, int z, Block block, int meta)
{		
	if(Minecraft.getMinecraft().thePlayer.capabilities.isCreativeMode = false){
		switch(meta){
		case 0:
			world.setBlockToAir(x,y,z);			
			break;
		case 1:	
			world.setBlock(x, y, z, Blocks.clay, 0, 1);

			block.dropBlockAsItem(world, x, y+1, z, 1, 1);
			break;
		case 2:	
			world.setBlock(x, y, z, Blocks.dirt, 0, 1);
			break;
		case 3:	
			world.setBlock(x, y, z, Blocks.sand, 0, 1);
			break;
		default:
			break;
		}
	}


}

You're assigning the field rather than comparing it.

 

Use

==

.

[jabelar]

How do you know it isn't working?  Is it crashing with an error?  If you're debugging an if statement just add console statements before and after to print out the value of the expression you're testing then confirm that the code is taking the path you expect.  If it is crashing then post the error messages.  Otherwise just trace the execution with console statements and you should quickly find any problem.

[Zer0HD2]

Alternatively, since it's a boolean, you can use:

 

if(!Minecraft.getMinecraft().thePlayer.capabilities.isCreativeMode)
{
    ...
}

I should have tried that, works now

thank you....

 

Now I have a quick question, how do I get my block to spread and update. I was able to get a working spread block, but haven't been able to get it to work with metadata blocks. This is the updateTick of the working spreadBlock *based on vanilla grass:

 

 public void updateTick(World world, int x, int y, int z, Random random)
    {
        if (!world.isRemote)
        {
        	
            if (world.getBlockLightValue(x, y + 1, z) >= 9)
            {
                for (int l = 0; l < 97; ++l)
                {
                    int i1 = x + random.nextInt(3) - 1;
                    int j1 = y + random.nextInt(5) - 3;
                    int k1 = z + random.nextInt(3) - 1;
                    Block block = world.getBlock(i1, j1 + 1, k1);

                    if (world.getBlock(i1, j1, k1) == Blocks.dirt && world.getBlockMetadata(i1, j1, k1) == 0 && world.getBlockLightValue(i1, j1 + 1, k1) >= 4 && world.getBlockLightOpacity(i1, j1 + 1, k1) <= 2)
                    {
                        world.setBlock(i1, j1, k1, this);
                    }
                }
            }
        }
    }

Is that method ever called? Did you set your block to tick randomly?

[Electrobob99]

Yes I have

 

[Elyon]

Are you sure the code runs?

 

Can you paste your entire class, preferably as a gist for line numbers and syntax highlighting?

ok here it is, I may have figured it out:

Now, let's see...

 

How long have you waited to see if your block spread?

Well I know I was able to get it to spread by giving it the flag of 3, but it seems to be slightly unpredictable.
