Animation 1px problem #Solved

Question

So...
Ball 20x20.
Jumps off from walls each time it touch it,but...
It jumps from Y walls <0 coordinate and >380 (works good)
But when I'm trying to set same for X - it stuck.

Aaaand...I can't get why :D
Works only with <0 && >379...but it supposed to be 380 ?

Answer 1

...Look like you prefer to use the long code
what I mean is
if (x < 0 || x>380){
speedx *= -1;
} if (y<0 || y>380) {
speedy *= -1;
}
*just replace else if with "if"*

Answer 2

if ((x<0 && speedx==-1)||(x>380 && speedx==1))
{speedx *= -1;}
else if ((y<0 && speedy==-1)||(y>380 && speedy==1))
{speedy *= -1;}

Answer 3

ya because of red color😵😵

Answer 4

change to the conditions above
to also take the current direction into consideration

Answer 5

replace "else if"
with just
"if"

That should be worked

After that replace
x=0 with x=100//For working beautifully

Answer 6

Btw btw
@Burey is so cool xD

Answer 7

nice code
did u saw my code of bouncin ball with marquee

Answer 8

@Burey
Yep,that works :)

Changed to

if ((x <=0 && speedx == -1) || (x >= 380 && speedx == 1)) {
speedx *= -1;
} else if ((y <= 0 && speedy == -1) || (y >= 380 && speedy == 1)) {
speedy *= -1;
}

Not sure if it goes out of limits now ,but whatever :D

Not realy ,I tryed to guess the reason of problem first of all...
And guess now I see it.

My first code can't check 2 conditions at once

So after Y bounce - it went in same step to X and instead of bounce kept moving...

So it was like 382 - 381 - 382 ...........untill other Y.

I choised Burey's code cause I thought yours wrong,thought you want me to put X "if" inside Y "if" and for sure I can say it will not work even without tests , that's the reason why I ignored it ,just misunderstood :)

I'm pretty slow at finding real reason :D
