Hi everyone. I made FartDistanceJob to detect if there is ground under my player, using Unity docs.
But it throws me this exeption: InvalidOperationException: The previously scheduled job ExportPhysicsWorld:CheckDynamicBodyIntegrity reads from the ComponentTypeHandle<Unity.Physics.PhysicsVelocity> CheckDynamicBodyIntegrity.JobData.PhysicsVelocityType. You are trying to schedule a new job FartDistanceJob, which writes to the same ComponentTypeHandle<Unity.Physics.PhysicsVelocity> (via FartDistanceJob.JobData.__TypeHandle.__Unity_Physics_PhysicsVelocity_RW_ComponentTypeHandle). To guarantee safety, you must include ExportPhysicsWorld:CheckDynamicBodyIntegrity as a dependency of the newly scheduled job.
I tried schedule it like this:
JobHandle distanceJob = new FartDistanceJob { playerInput = playerInput }.Schedule(state.Dependency);
distanceJob.Complete();
But it says: InvalidOperationException:
The UNKNOWN_OBJECT_TYPE has been declared as [WriteOnly] in the job, but you are reading from it.
And
UnityException: GetOrCreateTrackerHandleImpl can only be called from the main thread.
Constructors and field initializers will be executed from the loading thread when loading a scene.
Don’t use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function.
How can I solve this and check ground existence
