Onwall

[ownerofbabylon]

I feel like an idiot but I just saw a post on why onwall would work and that made me think about somthing. Can someone explain to me how onwall works?

[SkooL]

if (onwall(x,y)) {thestuffgoeshere;} So if the NPCs x and y coordinates are on a wall/tile that cannot be walked on...the things in the brackets occur.

Ok, the main thing i have a problem with is how would you get a whole area like that? Sorta make a block of the x and y. So say you wanted somthing to happen when a whole certain area was touched?

I dont understand...Are you looking for a certain area? Or are you just checking to see if a large chunk of land is onwall?

I suggest you use
!onwall(x,y) to do player onwall..
player onwall kinda bothers me to make and to explain..
I dont have any examples . i had some but i dont know where it ended up..
I suggest you make an array with like .25,.5,.75,1,1.25 and then just the values for the x,y . and theres a tutorial by Ace too that explains well which tiles Graal checks for the player..

say for mining or fishing u just want the weapon to fire on a certain block of area. Thats what I mean

if you just wnat like fishing in the water then you use board..
if you want mining but like on a npc u made then use triggeraction or callnpc+testnpc..

here is a code for board[] on water =)

NPC Code:

---

this.x=int(playerx+1.5+(vecx(playerdir)*3));

this.y=int(playery+2+(vecy(playerdir)*3));

this.canfish=board[this.x+(64*this.y)];

  if (this.canfish=322) { fish code here }

---

322 is the index of the water tile(the swimmable one)

Well for that you jus wanna use board[index] to tilecheck....someone check my figures on this cause I dont got my notes on hand, and I almost never use board...but it goes like this (I think)

board[x + y*64] = bx + by*16

x and y are is the loc you want to check, and bx and by are the x and y values of the tile it returns (on the tileboard on the bottom right of the level editor)...I forget the math too...but you can use a formula to pull bx and by out of the responce it gives you...
(someone post the math?)
