Function physx_sys::PxController_invalidateCache_mut

pub unsafe extern "C" fn PxController_invalidateCache_mut(
    self_: *mut PxController
)

Flushes internal geometry cache.

The character controller uses caching in order to speed up collision testing. The cache is automatically flushed when a change to static objects is detected in the scene. For example when a static shape is added, updated, or removed from the scene, the cache is automatically invalidated.

However there may be situations that cannot be automatically detected, and those require manual invalidation of the cache. Currently the user must call this when the filtering behavior changes (the PxControllerFilters parameter of the PxController::move call). While the controller in principle could detect a change in these parameters, it cannot detect a change in the behavior of the filtering function.
