Question by Caiuse · Jul 10, 2012 at 02:58 PM · linqaotjittoarray

JIT exception with ToArray() Linq

Trying to compile to iOS and I'm getting the following exception:


ExecutionEngineException: Attempting to JIT compile method '(wrapper managed-to-managed) UnityEngine.RaycastHit[]:System.Collections.Generic.ICollection`1.CopyTo (UnityEngine.RaycastHit[],int)' w$$anonymous$$le running with --aot-only.


I've done my research and I understand that JIT is "Just In Time", and I need "Ahead Of Time". I know that it's to do with the declaration wit$$anonymous$$n my line of code. What I want to know is how I can stop the ToArray() throwing an exception and declare the type?

 var $$anonymous$$tPoints : RaycastHit[] = Physics.RaycastAll(ray, rayLength, layerMask2).OrderBy(function(h){ return h.distance; }).ToArray();

ToArray() is a Linq method.

Most of Linq extension methods from Linq for Collections are not working with IEnumerables on iOS since they require AOT runtime compiler w$$anonymous$$ch is not supported.

However there is a Linq for iOS library on Asset Store that is similar to Linq but doesn't require a runtime compiler. So you can use it on iOS and ToArray() method will work with t$$anonymous$$s library.
