How Do Yo Check if a Level is a Multiple of 10?

I'm probably missing some very easy mathematical equation, but, I want to check if the player is on level 10,20,30, and so on. If that happens, a boss will appear, but how do I check if a level is a multiple of 10?

IF X MOD 10 = 0 Then X divides by 10 evenly, with no remainder.

IT works, thanks! I didn't know about mod

the thing I don't like of mod is that it does not work for negative numbers: when I write "-7 mod 10" I expect to get 3, not -7. Anyway its easy to code one's mod.

Anyway the syntax is

IF X MOD 10 = 0 Then makebossappear(cool, powerfull, supemissiles)

Theres anohter potential way,

if int(x/10)*10 = x
  ;Devidable by 10
  else
  ;Not devidable by 10
  endif

mute point tho, as sswifts provided the answer! :)

I am still shakey on MOD squad myself so I would divide the number by 10 and then by itself... if the answer was exactly 1 then viola! you have achieved another level of base 10.

MOD just gives you the remainder after dividing by the specified number - if it's 0 then the number divides into the original exactly.

just use ABS(X) MOD 10 to avoid probs with negative numbers, but then you shouldn't have a level numbered below 1 anyway I would think.

Najdorf:

MOD still gives a zero answer on multiples of -10, i.e.,

IF X MOD 10 = 0 Then makebossappear(cool, powerfull, supemissiles)

will still work at -10, -20, etc, for multiples of 10

Regardless you could use

If MOD abs(10) = o then makebossappear(cool, powerfull, supemissiles)

abs is absolute value.. makes a neg number a pos and leaves pos as pos.

shagwana - better don't use INT this way since it will round floats. Instead use

x_floor=floor(x/10)*10
if x - x_floor = 0
  ;multiple of 10
  else
  ;Not multiple of 10
  endif

function qWrap(Quick,low,high)
if quick>high then quick=low
if quick<low then quick=high
return quick
end function

works for me. if your using whole numbers

Neo, What happens when you Qwrap(15,0,10)? You get 0, not 5 :P

ABS(X) MOD 10 as Vorderman said.... will do :)
