vecx and vecy is weird but it works.
erm ill try to explain what it does and how it does..
what it does is ..
it returns a -1 or a 0 or a 1 . depending on the playerdir. and its used to move things ''forward'' or backwards or whatever..
if you do
playerx+=vecx(playerdir);
playery+=vecy(playerdir);
it will move the player 1 spot forward. (the way hes facing)
how it does is simple..
ill tell you in english
if playerdir is 0 (up) vecx returns 0 and vecy -1
if playerdir is 1 (left) vecx returns -1 and vecy 0
if playerdir is 2 (down) vecx returns 0 and vecy 1
if playerdir is 3 (left) vecx returns 1 and vecy 0

its also usefull for triggeraction
triggeraction playerx+1.5+(vecx(playerdir)*2),
playery+2+(vecy(playerdir)*2),blabla;
