That's pretty much the easiest way to debug, by printing out the variable. Here's a page you can use to convert from many types to a string for printing if needed.

Well i guess i will have to deal with it with that method, not exactly what i had in mind but if there are no other ways, that will do.
Thank you.

From here:

I'd like to know the difference between the two, please.

Is there any way to add an event handler without MAPINFO? I can't add such a thing because it needs to work in earlier versions where ZScript (and thus event handlers) didn't exist.
There is an EventHandler.Create function mentioned in a comment, but no such function actually exists.

DoEffect is called from the owner's Tick function to ensure that all is done in a defined order. If you do some bookkeeping in there it may get mixed with other DoEffect functions by real inventory items so that the actual state of the player may only be partially affected by them when your function gets called.

Okay. Can you explain why EventHandler.Create doesn't exist anymore? It would be quite useful right now.

Nevermind that, apparently MAPINFO ignores unknown properties, so I can use it anyway.

At the moment you cannot define any direct interactions between a linedef trigger and ZScript so you have to go through ACS and call a custom ZScript function through there.

Code: Select all

Line 25 in file "/tmp/SLADE3/SCRIPTS.acs" ...
/tmp/SLADE3/SCRIPTS.acs:25: Function scriptcall is used but not defined.
Well, how to get this function?

You'll need an ACS compiler that's up-to-date enough to support it. I'd recommend gdcc-acc, it comes with multiple benefits over normal acc: viewtopic.php?f=44&t=32078

Graf, is it safe to introduce our own STAT_ numbers for thinkers? (I.e. using 7 for a stat number) Also, is there a set range for thinkers where the Tick function is not automatically called, besides 1 through 6 (STAT_INFO to STAT_STATIC)

How to check for ZScript support thru ACS and use a fallback way if it isn't supported?
