Script priorities

[inmortal]

I have a little question:

During my short use of AGS i've realised there are three repeatedly_executed scripts:

-One at global script
-Another one for each room
-And one which I don't know what is for, called repeatedly_executed_always at global script

I need someone to tell me which scipt has the preference.

I mean: if I type "a=2;" at globalscript repeatedly_executed and I type "a=3;" at the room repeatedly_executed script and "a=4;" at repeatedly_executed_always.
Whats "a" value at the end?

Thanks

I'm sure someone else will be able to answer you, but I just have to ask - I'd understand, with other functions, the need to know the order in which AGS processes its stuff... but with rep_execute? It's not an issue you're likely to ever need to resolve. Rep_exec is for those things that are repeatedly being executed. For a default gamespeed, that's 40 times per second. In practical terms, you'll hardly ever need it for stuff when you need such definite values.

Here's something you can try yourself - do exactly what you proposed to do in your example, and add, after each line of code, something to make the game display "a" in a GUI label. See what happens.

Again, this is not at all a practical question, due to the intended use of rep_exec. Can you give an example of a case where the priorities could be a relevant factor?

Code: ags

//At global script rep_exec
if(mouse.Mode==eModeInteract)label.Text="Interact with @overhotspot@";

Code: ags

//At room script rep_exec
if(Game.GetLocationName(mouse.x,mouse.y)=="window"){//if mouse is over hotspot window(i dont mind the mouse mode)
label.Text="Look through the window";
}

Not only you replied with a valid example, you just exemplified using code that you can actually use to answer your own question. Try that code out and see what happens.

I don't *know* for sure, but I believe room script is processed first and global script last. Not sure. Try out your own example, see what happens.

Right tried it out and room script had preference.

Now, what's the difference between rep_exec and rep_exec_always???

[Rui 'Trovatore' Pires]

I'm sure that's explained in the manual, but I can understand it's not immediatly obvious to a recent AGSer.

Basically, rep_exec has a catch - it would not run during blocking events. If you had a pop-up GUI displayed, or some object/character was running a blocking animation, or a Display window was on, rep_execute would pause. Rep_exec_always, on the other hand, runs away *all the time*. Use with caution, and sparingly, young Luke.

In the manual under Understanding blocking scripts it explains everything Rui just said. Though it's understandable how getting from "how does rep_ex differ from rep_ex_always" to that page.
