lua message dispatcher for entity.userdata

[flachdrache]

Moin,

i like to have all "fire an forget" effects handled client side alone e.g. decalTime and other time based effects.

 

So far i think following objects would be needed

a global timer
message dispatcher
eventSystem

 

basically the idea is to set entity keys on new effects ( like a decal ). Like ... spawn decal, set timer, if decalTime over send message to free itself. I want to solve that in the OOP way but iam somewhat puzzled where to start ?! How do i collect / record new entitys added to the world from given moment ?

 

any help appreciated

Assuming you made some kind of EntityFactory script in Lua, and just hooked in the base.lua entity:Spawn function to log in your factory that an entity was created you could do that. Assuming you are going for an all Lua approach.

Hey Tyler - in fact my assumptions are partially based on some of the lua classes you posted.

This event message dispatcher might work in the lua world alone, setting postprocessing fx and other client behavior might be controlled in source code.

 

However, if the player steps on the firepit i dont see a reason why it shouldnt controll timing a fire emitter and such.

 

I basicall want to put a timer entity in the scene which counts the seconds the game is running and if a behavior is at hand ( a new decal is spawned ) the message dispatcher class notes the event system that it should free this decal in 15 seconds ... how do i collect those data ?

 

 

PS:

The non-OO approach would be to "simply" have the entity send a message to itself - which free`s itself after a delay.
