Arraymaker: How to replace a Gameobject at a specific index?

[ToxicFrog]

Hello fellow Playmakers,

I have had some great success using Arraymaker, but have run into a problem that I'm having a hard time solving:

I have actions that add and remove gameobjects to a list as certain actions are performed.

In some circumstances, I need to replace the gameobject at a specific index with another gameobject.

For example, let's say I have a list that looks like this:

Item 0: GameObjectA
Item 1: GameObjectA
Item 2: GameObjectA
Item 3: GameObjectA
Item 4: GameObjectA

I want to replace the gameobject in Item 3 with GameObjectB, so it would look like this:

Item 0: GameObjectA
Item 1: GameObjectA
Item 2: GameObjectA
Item 3: GameObjectB  <--
Item 4: GameObjectA

I appreciate any help, and will reply with results.

Thanks!

Hi,

 For this you use the action "ArrayListSet". you target the arrayList proxy, you give the index and the value to set at that index.

I must be doing something wrong.

Here's what I've got:

"Seq" is an int, the number of tiles in play
"Seq-1" is also an int that I use to specify the index I wish to modify the contents of

"Swapper" is a gameobject that I want to replace in the list

Here's the sequence I've got:
1. Set Int Value of "Seq-1" to equal "Seq"
2. Int Add -1 to "Seq-1" (so now it will specify the next-to-last index in the Arraylist
3. Array List Set. Use Owner, in the proper Reference, at Index "Seq-1". Data type "GameObject", variable "Swapper".

Yet when I look at the ArrayList, it has not inserted "Swapper". Instead, it shows GameObject (none).

Thoughts?

Hi,

 you'll need to double check few things:

-- are you properly targeting the right proxies? if you have several arrays or hashtable in one gameobject, you must use unique "references" else it picks up the first one

-- if it's a prefab, are you sure the instance properly host the pointer to gameobjects in fsm variables? remember you can't keep a pointer to a gameobject in a prefab, it will get lost.

-- if you are in the same array ( if you want to swap two items in the same array), then be careful that you don't get mixed up with keeping track of the variables, make sure you have 2 variable, one hosting the value of first index and one the value of the second index, then you can do the deance of swapping.

 I am doing this a lot, so I am 100% sure this works, make sure you go over the process step by step first in your fsm, put  a breakpoint as well on key states, that will help.

 Bye,
