How can I call a sub and tell it to stop executing?

[Dude1]

Hi, I have a little problem.

I have a main loop something like:

Do

'code here

if Collision then Explode

Do Events
Loop
--------------------------------------------
Sub Explode()
'explosion code
End sub

So I have a loop that checks for collisions in my game and if there are any, it calls the Explode sub. Now my question is, how do I stop the Explode sub from executing after a certain amount of time. The timing itself is not the problem, I can use timer interval, but how do I STOP the explode sub?

Thanks a lot!

You can use Exit Sub....

[Dude1]

How? Can you tell me? I tried making a boolean and saying that if it is falls then Exit Sub but nothing happens!

I hope you get a better answer than this, but in the mean time try putting in a few more DOEVENTS (up to 10) and see if that helps. it's gonna slow you down for sure though.

in the timer

mycount = mycount+1
If mycount = 1000 '(or whatever) Then
Timer.Enabled = False

in the explode function

Sub Explode()
If mycount = 1000 Then Exit Sub
'explosion code
End Sub

hm well why don't you have your explode sub do something like that

sub explode (timeToDie as long)
TimeToDie = gettickcout + TimeToDie
do
    'do whatever you sub is supposed to do
loop until gettickcount > TimeToDie
end sub

but what if he passes 100000? How does he get out of it if he wants to abort the explosion? At that point he's in the loop. How can timetodie be interactive?

[/\/\isanThr0p]

well in case it needs to be interactive he could use a global var and set it to 0, so the loop would terminate.
but from his question I couldn't see he wanted interactivity, I know there have to be better ways than using a global variable. I will post one when I get home.

you could set up a boolean in your main loop

if bolExplo then Exlplode

in that case you would have to change your exlpode sub though that is has no loop of its own, because it is already looped in the mainloop.
Now you could change bolExplo everywhere in your mainloop.

another way to do it would be to set up the explode thing as a class. than you could have a boolean value as property of the object (created from that class) and the explode code as a method in which it checks the property.
