I am making a mod and in this mod when it checks to teleport the player it was checking if the blocks that the player would tp were air. It worked fine in vanilla but once railcraft was added in my modpack the residual heat were keeping the player from spawning since they were not air. I am trying to find a way to see if the blocks in the teleport destination are soild, meaning any block the player can not walk through. I have tried isSolidCube and isOpaqueCube and both allowed the player to teleport into these blocks. I want things like water and air like blocks to allow the player to to but chests and glass and other solid blicks to prevent the teleport

I prefer to use the Material to check:

if (!block.getMaterial().blocksMovement()) {
  // not a solid block, so go ahead and teleport if that's what you want
}

Managed to get it to work running a test using

if(world.getBlock(x,y,z).getCollisionBoundingBoxFromPool(world,x,y,z) == null){
//the block at x y z has no collision box
}

Thanks for that tip. Since it requires less argumentsbit would be easier to use. Thanks. And i love your zss mod

Why not use

Block#isBlockNormalCube()

? It checks

Material#blocksMovement()

and if the block is rendered like a normal block.

Be careful with that one. I don't recall if it is that method or one that is named very similarly, but one of them is client-side-only.

Your right, that method is client-side-only. Didn't even check for that one. You can always go with

Block#isNormalCube(IBlockAccess,x,y,z)

or one of the suggestions above.

Your right, that method is client-side-only.

 

Oh, I've been bit by that method at least twice.

isNormalCube is a bad way to determine if a block is solid. Blocks like Fence would return false even though you would consider them to be solid.

You can also check if(world.getBlock(x, y, z) instanceof Blocks.air) because the residual heat from railcraft extends BlockAir.
