Hello everyone, I’m having some trouble placing the enemy sprite on the road. It keeps spawning above the road and when I try and place “set enemy position,” to the desired place im getting an error code “sim error: failed cast on null.” If someone could tell me why the error is happening or how to fix it? thanks.

The issue is that you haven’t defined what the bogey sprite is so the simulator cannot find it. I would suggest setting its position when the sprite is created (on created sprite of kind block)

I just moved the set bogey position block into the on game update block
