Just a quick noob question from me. I want to use skills in WED to define some stuff for elevator, door etc. I know how to do that by placing commented lines something like this: "// skill1 height 0 " but the problem is, that I already use skill1 (1 - 6) to define movement vectors. So my question is, how to use for example skill67 so it appear in WED as a first skills? Thank you.

You cant. End of story.

WED is hardcoded to use the first 20 skills of an entity and no others.

(this was true last time I used WED .... last year sometime...)

Hope this helps.... (and is correct )

You can!
At least this way:

//skill1: health 100
//skill2: mana 50
action my_action()
{
my.skill67 = my.skill1;
my.skill73 = my.skill2;
for(i = 0; i < 6; i++) my.skill[i] = 0; //reset skill1 to skill6
...
}

lol, though it kind of prevents you from setting any movement variables that are required.

if you were going to do it that way you'd need to use global variables and use the behaviour panel, then use the method you've shown

I think Superku's way should work, assuming 3run ONLY has
movement vectors down in the first 6 skills.

Cause (to my mind) the movement vectors are really only useful on a
frame-to-frame basis, and would normally start at zero anyway.

So if they are not being used as valid vectors until the entity action LOOP
has started, then 'smuggling' the other skills in through them is a great idea...
