c# - How to Position an Object Separately from Randomized Objects in Unity? -

in 2d game have randomized objects spawned 4 5 clones each time run game. problem have different object want spawn 1 clone, , position appear after last clone of randomized objects have in game.

the objects randomization works in game, need separate object want spawned independently , after last clone of randomized objects.

this code using 1 line of attempt spawn independent object: (the code taken this tutorial)

 using unityengine;     using system;     using system.collections.generic;       //allows use lists.     using random = unityengine.random;      //tells random use unity engine random number generator.      namespace completed      {          public class boardmanager : monobehaviour         {              // using serializable allows embed class sub properties in inspector.

when instantiate final gameobject, you're not giving position. understand want position in same place last randomly positioned gameobject, offset in x axis. you'll need vector3 contains position of last randomly spawned gameobject, i'll call lastrandompos. assume know how value, if not leave comment , i'll include in answer. can pass position when instantiating final gameobject:

var objpos = lastrandompos; objpos.x = objpos.x + <however want offset in x>; instantiate(obj, objpos, quaternion.identity); 

edit: easiest way position of last random object set class-level variable every time instantiate object in layoutobjectatrandom. declare in class scope, example underneath declaration of gridpositions:

private list <vector3> gridpositions = new list <vector3> ();   //a list of possible locations place objects. private vector3 lastrandompos; 

then when instantiate random object can set variable keep track of spawned:

instantiate(tilechoice, randomposition, quaternion.identity); lastrandompos = randomposition;
