PhysicsLoopHook

Shared Openplanet plugin that owns one native physics hook and dispatches registered callbacks.

Consumer plugins should only register and unregister callbacks.

Add a dependency in your plugin:

[script]
dependencies = ["PhysicsLoopHook"]

Then register a callback:

int g_CallbackId = -1;
PhysicsLoopHook::IPhysicsLoopCallback@ g_Callback;

class MyPhysicsLoopCallback : PhysicsLoopHook::IPhysicsLoopCallback {
    void OnPhysicsLoop() {
        // Runs after the race physics step.
    }
}

void Main() {
    @g_Callback = MyPhysicsLoopCallback();
    g_CallbackId = PhysicsLoopHook::RegisterCallback(
        "MyPlugin",
        g_Callback
    );
}

void OnDestroyed() {
    if (g_CallbackId >= 0) {
        PhysicsLoopHook::UnregisterCallback(g_CallbackId);
        g_CallbackId = -1;
    }
    @g_Callback = null;
}
