ZDoom

This is probably due to some weird formatting error or something, but here goes!

I was attempting to make a replacement for the chainsaw that would alert monsters as soon as it is selected, as well as during its ready state. To achieve this effect without screwing up the animations or anything, I added the following line to the beginning of both the ready and select states: Whenever I boot up DOOM it spits out the following error: I have no idea why it's doing this. I've tried looking up the error online and seeing what was causing it for other people, but none of these problems apply to my code as far as I can tell. In fact, until I added this line, the code worked perfectly.

Here's a link to my WAD thus far:

The problem is how you're specifying your arguments for A_AlertMonsters. The interpreter assumes that a space after an action function is a new-line, so it wants the next string to be a string of 4 characters to reference a sprite, and is instead getting "512."

What you should be doing is using parentheses to supply an argument to a function, like this:

Of course. I forgot all about that. Thanks!

By the way, your tutorials on Gunlabs were what got me into making my own DOOM mods. I still use them today, actually.
