[Trigger] OP Limit (question)

[JaysProjex]

I've searched around I cannot find a informative answer nor have I found anything that is detailed enough to specify what this is exactly, is 1 integer (loop) adding a +1 to the operation? What exactly is adding to the operation I'm blind here.

If a thread can with stand 33,333 or 25,000? I question this because my loops don't nearly even hit 100 even though I'm running a sequence of about 5 Integer loops of them so we then have a total of 500 loops. Am I missing something, why does it stop at only 500?

Op-limit is the collection of all code in a thread. Every action adds bytes of code which can be infinite. To stop the infinite part from happening WC3 has an op-limit. This limit says when all code adds up to a certain amount of bytes the thread is stopped.

Blizzard created a 'roof' for loops to prevent users from using infinitive loops (afaik the oplimit for integers is 8168 or something like that)

The array limit is 8191.

300k micro ops, every little instruction costs something. There was a price list somewhere but I do not find it anymore. Iirc, most stuff was like 4, but that really means every little thing like reading a variable, writing to it, arithmetics, control structures like the start/end of a loop, comparisons, returning, function calls etc. That adds up and since function calls can be nested and the execution may vary (e.g. with ifs you can go different branches), there is not a good way to determine the burden of a function at compile time.

But yeah, you should separate what does not belong together anyway, open a new thread for functions you know may be expensive and avoid algorithms with a high amount of iterations not only because of the op limit but general performance.
