Most common reason a game crashes. (with no error message)

[vuevuevue2002]

I have a map that crashes at what seems like random times. The game just closes immediately and there is no error message. I assume there can be many reasons why this happens but i want to know what the most common reasons are.

EDIT:
Thanks for all your input. I've come to understand a bit more about mapping but here is where i am on my map. I'm pretty confident it isn't the triggers that are causing this no error message crash since i've checked for anything i could think of related to infinite loops in my triggers. I'm thinking now that it's the ai script. I use the AI Editor in WE and then i export the script. Then i open the script with notepad and change the hero settings so that i can have custom heroes with custom abilities that learn abilities over lvl 10. Here's where i think the problem is. When i make the Ai using a custom hero learn custom abilities over lvl 10 this problem seems to happen. However as i am testing right now with a normal hero with its normal abilities and the map seems very stable.

Another problem besides crashing without a error message is the short (i'm talking half a second or less) pauses during gameplay when i have the custom hero, abilities, etc edited in the script.

I can only guess it's not easy and i hope it doesn't involve learning a bunch of jass or scripting >< but what is going on?

Too many units on the map over a long time or an infinite loop in the triggers

thanks for the reply. I'm not sure i entirely understand what you mean. Can you give me an example of a infinte loop?

 

[Vegavak]

A loop that never stops?

 

[zandose]

loop
endloop

There ya go

 

[vuevuevue2002]

lol. I mean an example of how a infinite loop would look in GUI (yea i still use gui >.>).

 

[PoZoR]

lol like

event: a unit dies
action: create 1 footman for red
kill last created unit

that would be an infinite loop

 

[vuevuevue2002]

Interesting.. I have another question then. Infinite loops can happen anywhere and cause a fatal error? Like an Ai script for example.

Well for triggers this is also an infinte loop, that crashes most games.

• Infinte loop
  • Events
    • Time - Every 0.01 seconds of game time
  • Conditions
  • Actions
    • Region - Center Region <gen> at possition of ((random unit in (playable map area)

This causes fatal crashes cause of leaks.
"Possition of a unit" makes the game make a possition, and this is run 100 times a second.
If the game last 1 min there would be 6000 leaks. Same as if youve placed like 10000 units in a map. Fatal crash.

For AIs, im guessin your goin to need to stop it, then start it again, instead of making it loop.

 

[Restor]

well, but it is fast way how to get back to windows while testing a map and want to quit wc3 quickly, just type some message and some "loop-trigger) will start

Or if someone is chating cheats in singleplayer maps, run this triger also, it is cooler than game-lost action

Way to figure things out:

Turn triggers off. If the map crashes, it's not the triggers. Etc.

Infinite loops don't give errors...

It just quits.

Oh and here are some more...

• Inifinite Loops
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
  • Actions
    • Unit - Order (Ordered unit) to Move To (Center of (Playable map area))

• Inifinite Loops
  • Events
    • Player - Player 1 (Red) Selects a unit
  • Conditions
  • Actions
    • Selection - Select (Triggering unit)

• Inifinite Loops
  • Events
    • Unit - A unit Is attacked
  • Conditions
  • Actions
    • Unit - Order (Attacking unit) to Attack (Attacked unit)

You'd pretty much know when it is infinite.

 

[vuevuevue2002]

Exactly. I think the problem is in the AI as i described above (now edited in the first post) but i don't really know how to spot it since all "loop" have a "endloop" in the ai script.

If you are using WE-generated AI script, i am sure there would be no infinite loops.
If you still want to find the loop in jass, here is a tip: each loop has an endloop, it just says where the loop sequence ends. However, loop without "exitwhen" command will be definetely infinite. (or with a senseless condition, like "exitwhen false")
