Stingray Events System and Mechanism?

Anonymous — Thu, 21 Jan 2016 03:44:47 GMT

What i want is to custom my own events for a given game unit, how to define,fire/dispatch,and listen to my own custom events in stingray?

Seems that events is not a core class for stingray ,and the stingray.Events is only an Interface to access firing events on xbox one?

Hi Woogway,

There isn't really a centralized event queue per se. Typically Stingray games use Unit Flow or Level Flow as a hub to handle responding to event triggers.

You can fire a named event for a given unit either in a Unit Flow graph or Level Flow graph (using the Unit > Unit Flow Event node), or in your Lua code (using the stingray.Unit.flow_event() function). A unit flow event like this is a named event that occurs only for a particular unit instance. If that unit's flow graph contains an External > External In Event node with a matching name, the unit's flow graph will begin evaluating at that node.

You can also fire level events from Flow (using the External > Level Event node) or from Lua (using the stingray.Level.trigger_event() function). If the level's flow graph contains an External > External In Event node with a matching name, the level flow graph will begin evaluating at that node.

Hi robbs,thanks for reply,

seems that, it's tough to define, fire,listen and handle events totally by lua,we must rely on stingray flow node(level/unit) to do that,right?

There isn't a built-in event manager component.

However, since you're looking for something that stays fully in Lua, you should be able to implement one or integrate a third-party module quite easily. A quick search turned up this module:

which seems to offer the kind of interface you're looking for.
