SystemUpdateOrder Class

Defines standard execution order values for update systems. Lower values execute first.

public static class SystemUpdateOrder

Inheritance System.Object → SystemUpdateOrder

Remarks

These constants provide a structured way to order system execution without magic numbers. Systems can use these values directly or add offsets for fine-grained control.\<example> \<code> // Use standard order public int UpdateOrder => SystemUpdateOrder.Physics;

        // Custom offset \(run right after physics\)
        public int UpdateOrder => SystemUpdateOrder\.Physics \+ 10;

        // Between two phases
        public int UpdateOrder => \(SystemUpdateOrder\.Physics \+ SystemUpdateOrder\.Collision\) / 2;
        \</code\>
