Generating object on Camera border,Spawning objects on screen border
Hi. I'm trying to spawn an object on the screen border. I've come up with this code, but I'm sure there must be an easier way to do it. Any help would be appreciated. Here is the code. The static values are generic screen borders, but I will change it later so that It can be dynamically adjusted based on screen ratio and size.
using UnityEngine;
public class MapGeneration : MonoBehaviour
{
float basex, basey, spawnx, spawny, xdist, ydist;
Vector2 basespawn, entryspawn;
public GameObject Base, entrypoint;
int entry = 0;
int entrypointsnum;
// Start is called before the first frame update
void Start()
{
entrypointsnum = Random.Range(2, 5);
basex = Random.Range(-6, 6);
basey = Random.Range(-3, 3);
basespawn = new Vector2(basex, basey);
Instantiate(Base, basespawn, Quaternion.identity);
while(entry != entrypointsnum)
{
spawnx = Random.Range(-8.4f, 8.4f);
spawny = Random.Range(-4.5f, 4.5f);
if (spawnx < 0)
{
xdist = -(-8.4f - spawnx);
}
else if(spawnx > 0)
{
xdist = 8.4f - spawnx;
}
if (spawny < 0)
{
ydist = -(-4.5f - spawny);
}
else if (spawny > 0)
{
ydist = 4.5f - spawny;
}
if(ydist < xdist && spawny > 0)
{
spawny = 4.5f;
}
if (ydist < xdist && spawny < 0)
{
spawny = -4.5f;
}
if (ydist > xdist && spawnx > 0)
{
spawnx = 8.4f;
}
if (ydist > xdist && spawnx < 0)
{
spawnx = -8.4f;
}
entryspawn = new Vector2(spawnx, spawny);
Instantiate(entrypoint, entryspawn, Quaternion.identity);;
entry++;
}
}
