Hi guys,

I'm having issues with stripping with Unity 2019.4.3f1 on ios.

The code stripping level is set to Medium.

Here is a portion of XCode console output.

--- Code: ---MissingMethodException: Default constructor not found for type HutongGames.PlayMaker.Actions.MissingAction
  at System.RuntimeType.CreateInstanceMono (System.Boolean nonPublic) [0x00000] in <00000000000000000000000000000000>:0
  at System.RuntimeType.CreateInstanceSlow (System.Boolean publicOnly, System.Boolean skipCheckThis, System.Boolean fillCache, System.Threading.StackCrawlMark& stackMark) [0x00000] in <00000000000000000000000000000000>:0
  at System.RuntimeType.CreateInstanceDefaultCtor (System.Boolean publicOnly, System.Boolean skipCheckThis, System.Boolean fillCache, System.Threading.StackCrawlMark& stackMark) [0x00000] in <00000000000000000000000000000000>:0
--- End code ---

link.xml files ued by Unity when building the code.


--- Code: ---<linker>
  <assembly fullname="mscorlib">
    <namespace fullname="System.Security.Cryptography" preserve="all" />
  </assembly>
  <assembly fullname="System">
    <namespace fullname="System.Configuration" preserve="all" />
    <namespace fullname="System.ComponentModel" preserve="all" />
    <namespace fullname="System.Net.Configuration" preserve="all" />
  </assembly>
  <assembly fullname="UnityEngine">
    <namespace fullname="UnityEngine.RectTransform" preserve="all" />
  </assembly>
  <assembly fullname="ConditionalExpression">
    <type fullname="PlayMaker.ConditionalExpression.ConditionalExpression" preserve="all" />
  </assembly>
  <assembly fullname="PlayMaker">
    <type fullname="PlayMakerFSM" preserve="all" />
  </assembly>
</linker>
--- End code ---

FSM State that causes this issue attached below.

Thanks in advance.

Hi,

 that's very odd, first time I see this error.

Do you get this only when stripping is set to medium?

Bye,

nope, it happens with High as well, only when stripping is low it works as expected.

jeanfabre:
Hi,

 something is odd here, MissingAction should not be required to begin with, it's something used during editing when a missing action is detected.

 Do you have errors in the playmaker editor?  Is it saying that you are missing some actions? if yes, fix that first ( clean up or import the missing actions) and try again.

Let me know how it goes,

Bye,

 Jean
