[Answered] tree

how do you make a tree only spawn on a certain block, like grass or dirt, or only be able to place that tree block on certain blocks like a cuctus(cactus can only spawn and be placed on sand)

try this, i have no idea if it works tho i got it from the BlockCactus.java

Code:


public boolean canBlockStay(World world, int i, int j, int k)
{
    if(world.getBlockMaterial(i - 1, j, k).isSolid())
    {
        int l = world.getBlockId(i, j - 1, k);
        return l == Block.grass.blockID || l == Block.dirt.blockID;
    }
    return true;
}


well you could use the code in trees already
