vp_wait

Method call snippet vp_wait(instance, 1000);

Pumps incoming and outgoing network traffic and fires any registered events. Required for most in-world method calls (e.g. vp_say()) and events to actually happen.

Parameters

These are the parameters that this method requires:

Parameter	Usage
VPInstance instance	Pointer to the instance this method call is intended for
int milliseconds	Maximum amount of time to pump (in milliseconds)

Returns

This method returns a return code integer, which indicates whether the call was successful or errored for any reason:

Return code	Cause
VP_RC_SUCCESS	Successful call (for methods that have a registered callback, it only means the request has been sent)
VP_RC_NOT_INITIALIZED	SDK not initialized with vp_init() yet

Behavior

• This will attempt to send all pending messages and receive all pending data within the given time limit
• All SDK events are fired from this method call
• If a value of 0 is passed, it could still fire a number of different events
• If there is nothing to handle, it will wait until the time limit. Else, it will return immediately after handling all pending data

Caveats

This method should never be called inside an event handler originating from a previous vp_wait() call. Doing so is undefined behavior and may break the internal SDK state. For example: <C> ... vp_event_set(instance, VP_EVENT_AVATAR_ADD, event_avatar_add); while(vp_wait(instance, 1000) == 0){} ... void event_avatar_add(VPInstance sdk) {

   char message[100];
   sprintf((char*)&message, "Hello, %s!", vp_string(sdk, VP_AVATAR_NAME));
   vp_say(sdk, (char*)&message);
   vp_wait(instance, 1000); // Undefined behavior

} </C>
