On 2nd thought, in my example I only care if a
car
is immersed within a
grape
or a
banana.
But I don't mind if a grape is colliding with a banana .![]()
So you're gonna need a double for loop, since you need to check 1 cellOne against the other 29.
Here's a close example doing that. Although it's 1D objects checking whether they're near each other.
But it helps to understand what's need to be done for your code. I hope so.![]()
