[Solved] What is the purpose of this action? +rep

• Custom script: call DestroyTrigger( GetTriggeringTrigger() )

I have seen this used with preloading things with the map initialization event. What is its purpose and why do it for map initialization? +rep for helpers

 

[Alain.Mark]

reduce handle counts in the map. but that thing is not that necessary.

 

[Aeroblyctos]

How much this reduce lag?

 

[SunTzu7387]

ya like does it reduce lag and save memory?

 

[Aeroblyctos]

Do you recommended to use this?

How much does this reduce lag compared to memory leaks for example?

 

[defskull]

Leaks should be taken seriously because it will be generated infinitely (well, until the system stops looping or stop its usage (for example leaking points that not been cleared))

While this trigger is a handle, which just not necessary to be destroyed but it can be destroyed

You can choose to destroy it or not, but leaks are a-must destroy

 

[Aeroblyctos]

I agree leaks should be destroyed, but what about whole triggers? Should they be destroyed too? Or is it not that necessary?

 

[Maker]

It is not that necessary, unless you dynamically create triggers as the game progresses.

 

[SunTzu7387]

is it necessary for map initilization events like once the trigger is done it wont happen again type events to save memory?

 

[Aeroblyctos]

unless you dynamically create triggers as the game progresses

What do you mean by this?

 

[WaterKnight]

You can create new triggers during runtime, makes sense with the UnitWithinRange-event for example. So you would allocate a trigger for each unit but all the units might appear through other means. So you always store more stuff in memory. In contrast to a static leak, the max consumption is not limited and can therefore become a problem.

 

[Aeroblyctos]

I never create new triggers ingame. Does this mean it's not necessary for me to destroy triggers?

 

[Maker]

Yep. Since you only have a few hundred triggers maximum, they won't require that many handles.

 

[Aeroblyctos]

Aah, I'm relieved. I think I have about 200 to 1000 triggers(not sure I'm not home).

What about events? I have one system that creates more events for a trigger. I believe the event count goes really high for one trigger, like 10,000. Is that a bad thing? Does that make lag?

 

[Maker]

It would be a good idea to recreate the trigger if the events pile up, and some of them are for units that do not exist anymore for example.

But if it does not seem to cause lag then just let it be

 

[WaterKnight]

Of course, I believe DestroyTrigger trashes the attached events. But rather, do you really need 1000 triggers?

 

[SunTzu7387]

Aeroblyctos.... Stop hijacking my thread!!! They keep on answering your questions and not mine... My question would be is it good to do this action after a map initialization event since you don't need the trigger anymore?

 

[Maker]

You can do it but, it doesn't make much difference destroying a few triggers.

 

[WaterKnight]

It's also another source of trouble if you do not do it right.

 

[shinji]

You should use that in the end of a trigger that you will use only once.

ok thank you guys for the help. i'm pretty sure thats all I wanted to kno. Solved. +rep to helpers
