unity3d - Random object in Unity -

i want make endless runner game. have 2 objects, 1 on top , 1 on bottom. players have jump between or squat on objects. made script creates objects, 2 object created on same position, players can't anything. how solve that? can check other objects on axis x, not collider?

basically asking give our level generator , game controller source code! have write 1 game. not because don't want give code because each game must have own.

for starters can:

• split game area matrix have array of sort, each cell can have game object or empty. game objects can have own local position within cell. 1 cell can't contain 2 game objects.

• have level generator tells game controller should spawn new objects. should implement in level generator prevent overlaps.

look @ psudo code:

void fixedupdate() {     if (player.transform.position.x + half_of_screen_width_plus_margin > nextx)     {         spawn(tmp[i].prefab, nextx);         nextx += tmp[i].distancetonext;         i++;     }  } 

half_of_screen_width_plus_margin game foresee what's coming

tmp[] collection of (not-instantiated) objects instantiated. each object defined arbitrarily.

as see script checks next position every fixeddeltatime seconds, , compares position x of end of screen next position x. if passed creates next object , change next position x further location.

if want use random generation tmp[] should change tmp. each instantiation next generated:

void fixedupdate() {     if (player.transform.position.x + half_of_screen_width_plus_margin > nextx)     {         spawn(tmp.prefab, nextx);         nextx += tmp.distancetonext;          tmp = generate_new_random_object();     }  }
