Actor's LifeSpan

Brood_of_Evil · Nov 4, 2001

Hi, I have a question and I would appreciate it if any one of you can help me with this. Anyways, my question is:

Is there a way to track the remaining time an actor has after it has been spawned. In my case this is a rocket, a sub class of a RocketMk2. What I want to do is, find a way to track it's remaining time in the world after it's spawned, and to make things more realistic, call it's "Explode" function about a second before it's expiration, instead of the rocked dissapearing all of the sudden.

Is the LifeSpan variable used only to set the...well, life span of the actor, or does it also keeps track of it? Or is there some function that returns this value?

The LifeSpan is the time the actor still has left. It keeps track of how much time is left. After the LifeSpan reaches 0 the Expired() function is called and the actor gets destroyed.

So if I write:

Timer()
{
//some code here

if(MyActor.LifeSpan == 1)
SomeFunction();
}

Will it execute the function when one second is left before it expires?

A LifeSpan of 1.0 is a second right?

Couldn't you spawn an explosion and hurt radius in the Expired() function?

That code won't work. SomeFunction() will only be called if LifeSpan is exactly equal to 1, which is most likely not the case. Generally, the == operator should be avoided when dealing with floats.

Yes, LifeSpan is measured in seconds.

[edit]
And yes, I believe you should use Expired().

Why don't you write:

Code:

SetTimer(Lifespan-0.5,True);

Timer()
{
Explode();
}

Or something, (dunno if Timer() is taken...)

If I didn't want to use the Tick or Timer then how would I overload the Expired() function?

I looked through the classes and only found Expired as an event.
BTW what are the Events for?

Thanks, well I used the expired function, you can overwrite is as any normal function, and set the code inside,

event means it is called by the game when something happens, but you can call it yourself ofcourse...
