Hello! I'm working on a Christmas mod and want to add a certain function but don't know where to go from here. I have it so when you place a star on the Christmas tree it checks to see if it's a Christmas tree and if true then it'll spawn presents under the tree but I don't want the presents to spawn underneath it right away. I would like if you have the right set up and then go to bed, the presents would spawn under the tree while you are sleeping or in bed. I hope this wasn't too confusing and would love some help! Thanks!

 

BlockStar Code:

public class BlockStar extends BlockFlower{

Random generator = new Random();

protected BlockStar(int par1, Material par2Material) {
	super(par1, par2Material);
	this.setCreativeTab(Wintercraft.WintercraftTab);
	this.setLightValue(0.9375F);
}


public void onBlockAdded(World par1World, int par2, int par3, int par4)
    {
        super.onBlockAdded(par1World, par2, par3, par4);

        if (par1World.getBlockId(par2, par3 - 1, par4) == Block.leaves.blockID

Use

PlayerSleepInBedEvent

.

Alright but what would I do for the par1world.setBlock X,Y,Z?

Hi

 

When you place the star, you have to save the coordinates somewhere.  Then, in the PlayerSleepInBedEvent, retrieve the coordinates and do your setBlock.

 

A good place might be in the player, i.e. you record the location of the last start that they placed.

-Suggest getting an NBTTagCompound from EntityPlayerMP.getEntityData() and using that - so it will get saved automatically.  You would need to do this on the server side, not the client.

 

Alternatively, if that's too hard, you could just use a static variable in a class somewhere ( it won't survive a save, but perhaps you don't care about that)

 

Nice idea by the way, I like it!
