character jumping - ABS() question

[GloriousIntruder]

Hi,

I am doing this tutorial for platforming game that is listed in the tutorial section (Fastloop Custom Platform Movement by David Newton). One part he listed in his event editor is

+ Grav("Player") <> 0
-> Start loop "gravity" ABS(Grav("Player")) times.

I cannot find the ABS() function anywhere and when I open this tutorial application and check on this expression I only found

-> Start loop "gravity"

All the ABS expression is not there at all. The tutorial doesn't explain much of this ABS function either. I am trying to make my character to jump.

My question is that what is ABS function and also why doesn't it show up in my application?

I don't know what you are doing... I can just tell you what abs does. It returns the absolute value of the input, so no sign. The result is always positive.
abs(10) = abs(-10) = 10
Make sure to check the documentation before asking in the forum for a function the next time.

Ah ok. I did search for it but it returns none. May be I give up to quickly or really desperate for an answer. Anyway thanks for clearing that up.

I remember someone else saying that I didn't include an explanation of what ABS actually does, too... I'm surprised that it just showed up as "Start loop 'gravity'" when you checked it, though. I would normally think that that was the result of opening it in an earlier version from the one I put together the example in, but I'm sure "abs" has been there for years.
