Some pen projects I see, including mine (https://snap.berkeley.edu/project?user=just_ng&project=Testing%20lol) the pen has some glitch effect or something like that. Is it supposed to be like that or is it just my computer?
P.S its very laggy 
Does it have a "glitch" effect on your computer?
Is that supposed to happen?
wut... why?
its the same as the change in y ...
-10
why is that a bug?
why w + s = 5? it can only be 1 or 0 or -1
so is the pen suppose to be like that or its a snap! bug?
And why is it very laggy?
if x = 5
If w key is pressed :
( ( 1 ) + ( 0 * ( -1 ) ) ) * 5 = 5
If s key is pressed :
( ( 0 ) + ( 1 * ( -1 ) ) ) * 5 = -5
Its not 0 x -1 x 10 = 0, but its 0 + -1 x 10 = -10
That is not a bug...
umm.... cuz its supposed to go down if the s key is pressed
