To create a job in Unity you need to implement the IJob interface.
IJob allows you to schedule a single job that runs in parallel to any other jobs that are running.
Note: A “job” is a collective term in Unity for any struct that implements the
To create a job, you need to:
- Create a struct that implements
- Add the member variables that the job uses (either blittable types or NativeContainer types).
- Create a method in your struct called Execute with the implementation of the job inside it.
When executing the job, the
Execute method runs once on a single core.
Note: When designing your job, remember that they operate on copies of data, except in the case of
NativeContainer. So, the only way to access data from a job in the main thread is by writing to a
An example of a simple job definition
// Job adding two floating point values together
public struct MyJob : IJob
public float a;
public float b;
public NativeArray<float> result;
public void Execute()
result = a + b;
