How to spawn Prefab to a certain position.

Thanks everyone. That JS snippet is working almost perfectly. but it spawns relative to the contact point. Now I'll try to figure out why after I post this, but maybe you guys can faster. in any case, i'm closer. So thanks! EDIT: I figured it out. I had moved the spawning script over to the trigger ins$$anonymous$$d of the player when I added the snippet to fix it, but experienced a crash. Then forgot to move it over again when I booted back up.

The second part, imagine this: There are three types of chests. WEAPONS class chests, POWER-UP class chests, and HEALING class chests. in each of those classes, there are 10 (or so) different types of chests that can be chosen. I.e. if Weapons>Sword/Axe/Dagger/??? Etc

I think I would need a script to perhaps choose an Int from 1 to 3, create an array I can fill with prefabs. Then, have the script check which int is chosen, and choose something from each array. OR, have the script randomly grab something with certain tags. Such as "Randomly choose an item with a tag 'weapon'/'health'/'power-up'.

I do think that an array/list would work better because i don't want the same thing to be chosen twice. Perhaps make it so once it's chosen, it's excluded from the list/array??

soo

 var chestType = Random.Range(0,4);
 
 function *something*{
 
 *Create weapons array*
 
 *Create Health Array*
 
 *Create PU Array*
 
 if(chestType == 1){
 *Choose randomly from Weapons array*
 *Then remove it from array*
 }
 
 if(chestType == 2){
 *Choose randomly from Health array*
 *Then remove it from array*
 }
 
 if(chestType == 3){
 *Choose randomly from PU array*
 *Then remove it from array*
 }

I don't really know any other language except JS. But I'm guessing that's the logic might run.

I'll help by suggesting you ditch Javascript. ;)

Any time you want several types of objects which have very similar properties / behaviors, you should consider making them variants of - or derivations of - a class. In your case, seems like you'd want a Chest class and a Door class, since you've got various chests and doors that do different things, appear different, etc, but are basically very similar.

Say you wanted to use the variant method, ins$$anonymous$$d of derivations. Frankly this seems more appropriate for a simple game. You'd have a single Chest class, but create several prefabs in the inspector. Each prefab can have its own model, material, whatever.

When you want a random chest, you have a list of those prefabs somewhere, and select a random element of that list to instantiate. The behavior of the chest/door/whatever could be driven by a switch that exa$$anonymous$$es the chest's enum "type" variable.

In response to your edited comment:
Yeah, you could remove whatever you chose from the array. For a simple project just go with that. However, it's good practice to keep prefabs untouched, including collections of prefabs. In that case, you'd keep a list of the indexes you've chosen, and keep choosing new random indexes until you get one that isn't on the list, use that unused index to instantiate the prefab, then add it to the list too.

EDIT: I have a code I pieced together. It spawns three level chunks. The first two from one list (normal levels), the third from another list (Boss levels). I plan on having this called only once per loadable session. So I think it's almost exactly what I need.

I want the player to reach a "safe zone" after getting through those three level sections. Then I want the previously loaded sections to be destroyed (to save on processing consumption), and a brand new section to be created. How would I do that? Assign those prefabs a class, and have the script destroy everything with that class identifier? Each section is going to be different, so each of them can all have their own different identifiers.

With this method, I wouldn't need to remove anything from the list, as each section would be calling from different lists. As far as I can tell, it's not too complicated to work. Would someone $$anonymous$$d taking a gander at the code and tell me if it'll screw me over down the road, or for a simple function, It'll work just fine? Thanks!

    var toSpawn : GameObject = prefab[Random.Range(0, prefab.Length)];
    var toSpawn2 : GameObject = prefab[Random.Range(0, prefab.Length)];
    var toSpawn3 : GameObject = bossLevels[Random.Range(0, prefab.Length)];
