PoolManager (More Null Ref Exceptions)
« on: June 13, 2013, 07:21:25 AM »
I just updated playMaker and PoolManager (and actions) and it looks as though trying to spawn something after reaching the maximum instance cap will cause the FSM to be locked in the Spawn state (even when there is an output for both Success and Failure).

The error is...
NullReferenceException: Object reference not set to an instance of an object
HutongGames.PlayMaker.Actions.PmtSpawn.DoSpawn () (at Assets/PlayMakerCustomActions/Path-o-logical/PoolManager2/PmtSpawn.cs:87)
HutongGames.PlayMaker.Actions.PmtSpawn.OnEnter () (at Assets/PlayMakerCustomActions/Path-o-logical/PoolManager2/PmtSpawn.cs:55)
HutongGames.PlayMaker.FsmState.OnEnter ()
HutongGames.PlayMaker.Fsm.EnterState (HutongGames.PlayMaker.FsmState state)
HutongGames.PlayMaker.Fsm.SwitchState (HutongGames.PlayMaker.FsmState toState)
HutongGames.PlayMaker.Fsm.UpdateStateChanges ()
HutongGames.PlayMaker.Fsm.UpdateState (HutongGames.PlayMaker.FsmState state)

Hi,

 Can you simply comment this line, it's a debug line, but this is odd, it should return the spawned transform. I'll run some tests, but last week I tested, and it worked, odd.

bye,

Hi,

 I haven't been able to reproduce these... could you send me a repro?

bye,

Here's a repro project. The spawner creates 3 balls (the instance cap) and then gets stuck in the spawn state rather than firing the Success or Failure outputs.

As you said, you can get around this by commenting out the debug line.

It looks like the debug statement should be moved to after this line:

if ( result != null){

Then everything should work as expected. Jean, can you update the unitypackage?

Cheers,
Alex
