Spawn Items/Units randomly from a list of points.

[BlackstarSirius]

I'm trying to make an item retrieval quest that spawns the item when the quest is initiated, but I don't want it to have one set spawning point, nor do I want it to spawn anywhere on the entire map. How do I make it so it spawns in a region that is selected randomly from a list of three or four specific regions?

Thanks!

I recomend you create an Integer Variable, let say "RandomItem"
Then, when the player starts the quest go.
"Set RandomItem = (Random integer number between 1 and 4)" The last number is how many regions you have.
After that create If/Then/Else Actions that look like:

If (RandomItem Equal to 1) then do (Item - Create QuestItem at (Random point in (Item Spawn Region 1))) else do (Do nothing)

If (RandomItem Equal to 2) then do (Item - Create QuestItem at (Random point in (Item Spawn Region 2))) else do (Do nothing)

If (RandomItem Equal to 3) then do (Item - Create QuestItem at (Random point in (Item Spawn Region 3))) else do (Do nothing)

If (RandomItem Equal to 4) then do (Item - Create QuestItem at (Random point in (Item Spawn Region 4))) else do (Do nothing)


Do that until you have it for all the regions, and you should be good.

It didn't work. Every time I test it the item appears in region 1.

The only variation of the trigger is that instead of creating the item, I move it to the region. And that I set the variable at map initialization, not quest initialization.

Would changing either of those make a difference?

Also, something interesting I just noticed is that the trigger is set to move the item instantly to the center of either region 1,2,3 or 4, but every time, it seems to have a slightly random variation in the region, not in the center.

I checked to see if I somehow crammed all the regions next to eachother, but that's not the case. :\

I moved it all into the same trigger to make it easier to view.

Rawr, it should be working. Try the If/Then/Else that is not "Multiple Actions" Then Post it here. It works for me XD

That wasn't working at first, but then I started my quest grabbing unit a few feet away from the quest giver and it worked just fine, weird. >.>

Thanks!

np, glad it worked

Another easier way would be to put the regions into a region array at start up

Set RandomSpawnRegion [1] = Spawnplace 1
Set RandomSpawnRegion [2] = Spawnplace 2
Set RandomSpawnRe...

then when it comes to making the item just go,

Spawn Item in RandomSpawnRegion [Random Integer between 1 and however many regions there are]

 

[Asomath]

it would be the same length. Instead of setting 1 variable, you would have to set the amount of regions. And instead of makibng a trigger for each region, you only have to randomize it to one. So, it would take the same amount of time.

But if you had to reuse those regions for 50 different items, then all that is needed is just one Event, instead of IF/THEN/ELSE taking up room.

Anyway, BlackstarSirius can choose his preferred way, and he can change the [Unsolved] to [Solved]

 

[Asomath]

hm your right on that point.

When you set regions to an array, and base the corresponding triggers off that array- the triggers become much easier to manage in the future for any future changes. As well as become much less cluttered.

Why scroll through 100 pages of IF = 1, IF = 2, IF = 3, when you can just use a For loop If check?

 

[Asomath]

Yes I get that now. It was stated. However, thanks for the help at pointing it out
