help ! how to generate object with specific area

I want to generate object nearby the player, but not out of bound for the game
some code below

Code (CSharp):

1.     void zombiegenerate()
2.     {
3.  
4.         pos = Random.insideUnitCircle * 10;
5.         pos = player.position + pos.normalized * ( 10 + pos.magnitude);
6.         Instantiate(zombie, pos, Quaternion.identity);
7.        
8.     }

i can generate the zombie nearby the player now, but when the player walk near to the bound, it will generate enemy outside the game, how can i avoid this ? any suggestion

 

If you know the dimensions of the world (e.g. a Bounds) or could "new Bounds()" it into existence, you could use myBounds.ClosestPoint(somePosition) to get a position that is confined to the edges of your world.

To further refine that, it might look funny if enemies are generating right on the edges of the world. So you might generate bounds that are somewhat smaller than the true size of your world.

 

bound may a bit complex for me (idk how to use it), i just simple solved by compare x y value to re spawn the object.

It won't get much easier than using bounds like @Lo-renzo said, actually it probably is easier than manually calculating x and y positions... check the docs.

If you were using navigation mesh, then you could just get the closest point on navmesh... but you didn't say, how you have setup your enemy movement.
