How to check if one GameObject is in the way of another GameObject?
I just started Unity two days ago, and it is quite a big fun, but I have a problem what I can't solve. Im making a 2D starship game where the enemy ships and asteroids are coming towards you and you have to shoot them. It's working fine, my only problem is I made the asteroids a bit faster than the enemy ships and it's quite weird when they are in the same y position line and the asteroid just go trough the enemy ship. My question is how can I check if there is an enemy ship in the way of the asteroid before asteroid spawning? Thank you for your help guys!
@gellihorvath At least in 3D: When you spawn an Asteroid, you can first rotate it to the Player via Transform.LookAt, and then do a forward-directed Physics.SphereCast. If it hits a Ship, you'd randomize the rotation again, and repeat the check until it finds a proper free lane.
Though a more interesting resolve for your issue may be for the Enemy ships to shoot backwards at Asteroids when they discover one (for which you can again use a SphereCast)...
You can do that by using raycast2D. Assuming all your 2D objects have a 2D collider, you can check from the astroids origin if anything is in front of them.The raycast will return true if anything is hit by the raycast2D.
