one question about custom draw code trigger

whether custom draw code trigger fire every time?
i write code pf(time); pr(); in draw code trigger .
Outcomeaccording to simulation velocity.
if i have some code which run every time,which trigger i write code ?

It is against the discrete event idea to fire a trigger every time unit.
And it makes a simulation run slow.
Only at events something will change in your model, so why have an event every time?
If you still want to have an event every time, you could use a UserEvent which gets repeated.

One side note: Why do you write your post with blue color and underline? It makes then more difficult to read. And if you ask specific people for an answer, you might not get one. A community is more a place where everybody helps everybody. So I would not limit this to special persons.

sorry it's my fault,my English is poor ,often trun to dictionary, i copy it so with blue color and underline.
sometimes,you can Realizing complex logic in one place,so there are some event you don't konw what time it happend,especial some conditon ,so you must check it every time,every time can be every second,Precision depend on your model.it is called"Centralized control distributed simulation",i used to use extendsim it can realize this function.so i think flexsim also can do it.
can you give me answer about first question?

Again, it is against Discrete Event Simulation if you use e.g. conditions like time() == 500. If you do not have an event at time 500 the condition will never be true. If you use time() >= 500 and one event is at time 400 and the next at time 700, your condition will become true at time 700.
If you use a user event at time 700 then you have your event at he exact time.

The custom draw code is fired very often, because it is like a Screen Refresh. I guess it is something like 24 times per second. If you increase the run speed, it will get fired less, I guess, but still every time unit? I don't know. But if you click in an ortho view, the custom draw code will fire.
So in this sense it will get fired more often than every time unit.

Like said, if you need a kind of a ticker you could use a user event which is fired every second. But this will slow down your model.

I agree with Tom's answers.

For debugging purposes, you might also want to look at the following thread which will allow you to execute centralised code on an event basis. The expression allows you to select which events cause the 'action' code to fire. Like Tom says, I still wouldn't recommended this for controlling model behaviour as it is evaluated on every event.

Note the action code will only fire when the value of the expression changes
