I've made an entity similar to a boat, and just like a boat it gets stuck on slabs, stairs, and even from transitioning from grass paths to normal dirt. I've been looking through the related code for a horse but I'm not finding anything that allows it to "climb" these things. Does anybody know what code allows me to do this?

I've settled on just climbing slabs, and here's something I've put together that seems to work well. If anything could be improved upon, let me know.

 

Spoiler

// Checks if entity is approaching a slab when it is on a full block
private boolean checkForSlab()
	{
		BlockPos currentPos = getPosition();
		boolean bool1 = false;
		switch(getHorizontalFacing())
		{
			case NORTH:
				bool1 =  world.getBlockState(currentPos.north()).getBlock() instanceof BlockSlab; break;
			case EAST:
				bool1 =  world.getBlockState(currentPos.east()).getBlock() instanceof BlockSlab; break;
			case SOUTH:
				bool1 =  world.getBlockState(currentPos.south()).getBlock() instanceof BlockSlab; break;
			case WEST:
				bool1 =  world.getBlockState(currentPos.west()).getBlock() instanceof BlockSlab; break;
			default:
				bool1 =  false;
		}
		
		int dX = 0;
		if(Math.abs(motionX) > 0.0001F)
			dX = (motionX > 0) ? 1 : -1;
		int dZ = 0;
		if(Math.abs(motionZ) > 0.0001F)
			dZ = (motionZ > 0) ? 1 : -1;
		BlockPos futurePosition = this.getPosition().add(dX, 0, dZ);
		Block futureBlock = world.getBlockState(futurePosition).getBlock();
		
		return bool1 || (futureBlock instanceof BlockSlab);
	}
