Physics Update

Beginner Programmer

When you need your logic to interact, query or otherwise modify the state of a simulation, you may need to do so right before or after physics updates. You can implement the ISimulationUpdate interface in your EntityComponent or Scripts to be notified of when simulation updates.

using System;
using Stride.BepuPhysics;
using Stride.BepuPhysics.Components;
using Stride.Engine;

public class MyPhysicsComponent : SyncScript, ISimulationUpdate
{
    public override void Update()
    {
        // Here you would call stuff you need to do every frame
    }

    public void SimulationUpdate(BepuSimulation simulation, float simTimeStep)
    {
        // Here is for stuff you need to do right before physics runs, 
        // sample player input, setting body velocities, etc.
    }

    public void AfterSimulationUpdate(BepuSimulation simulation, float simTimeStep)
    {
        // Here is for stuff you need to check right after physics ran, 
        // check if an object collided with anything, if it's on the ground, 
        // if it failed to increase in height when jumping, etc.
    }
}
