SystemUpdateOrder Class

Definition

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

C#

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;

Text Only

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

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

Fields
Animation	Animation systems \(e\.g\., skeletal animation, sprite animation\). Order: 400
Audio	Audio systems \(e\.g\., 3D audio positioning, music transitions\). Order: 600
Collision	Collision detection and resolution. Order: 200
EarlyUpdate	Early update phase \(runs before main update\). Order: -25
Input	Input processing \(e\.g\., reading keyboard, mouse, gamepad\). Order: -100
LateUpdate	Late update phase \(e\.g\., camera follow, UI updates\). Order: 800
Particles	Particle systems and visual effects. Order: 500
Physics	Physics simulation \(e\.g\., velocity integration, position updates\). Order: 100
PostCollision	Post-collision processing \(e\.g\., trigger events, damage calculation\). Order: 250
PostInput	Post-input processing \(e\.g\., input smoothing, dead zone handling\). Order: -50
PostPhysics	Post-physics phase \(e\.g\., physics cleanup, constraint solving\). Order: 150
PostUpdate	Post-update phase \(runs after main update but before physics\). Order: 50
PreInput	Pre-input processing \(e\.g\., input buffering, replay systems\). Order: -200
PrePhysics	Pre-physics phase \(e\.g\., applying forces, setting velocities\). Order: 90
PreRender	Pre-render preparation \(e\.g\., frustum culling, visibility determination\). Order: 1000
Update	Main update phase \(default for most systems and behaviors\). Order: 0
VeryLateUpdate	Very late update \(e\.g\., final position adjustments, look\-at systems\). Order: 900
