Okay, so I wrote a script that’ll allow the game player to jump with the
touch of a button. This script, I wanted a method that’ll adjust the
distance in which
the game player jumps, based on the farthest passible tile. To define
the method, I used a ‘for i’ statement with 0 to the max distance, for
each passible ‘space’ he can jump, I push the value into an array named
‘@spaces’, respectively.
def jump_dist
@spaces = []
case @direction
when 2 # Down
for i in 0...Jump::Distance
if passable?(self.x, self.y + i, 2)
@spaces[i] = i
return @spaces if i == Jump::Distance
end
end
when 4 # Left
for i in 0...Jump::Distance
if passable?(self.x - i, self.y, 4)
@spaces[i] = i
return @spaces if i == Jump::Distance
end
end
when 6 # Right
for i in 0...Jump::Distance
if passable?(self.x + i, self.y, 6)
@spaces[i] = i
return @spaces if i == Jump::Distance
end
end
when 8 # Up
for i in 0...Jump::Distance
if passable?(self.x, self.y - i, 8)
@spaces[i] = i
return @spaces if i == Jump::Distance
end
end
end
end
…Maybe I wrote that a little oddly, correct me if you know a better
functional method.
Anyways, next I test it with ‘print(jump_dist)’ whenever the player
‘jumps’ and it returns 0…3 (3 is Jump::Distance, BTW)
So basically, instead of returning an array, it returns a Range.
How do I get this to return me an array of only passable ‘spaces’, and
secondly how do I pull the highest value out of that array?
