almost every comment on my fish hunt and fish chomp games has told me that i have a problem. if an arrow key is pressed your fish gains speed going in the direction of the arrow. this will make your fish go off screen if you keep going in that direction. i want to make a way that when the key isnt pressed that the fish will come to a stop but all my scripts havent worked. this is what i have so far

<when green flag clicked>
<forever>
<if><key[ up arrow pressed ]pressed?>
<change{ y velocity }by( 0.2

this makes my fish go up and increase in speed if that key is pressed.
i have tried this to make my fish come to a stop

<when green flag clicked>
<forever>
<if><key[ up arrow pressed ]pressed?>
<change{ y velocity }by( 0.2
<end>
<if><<  <not>  >><key[ up arrow pressed ]pressed?>
<repeat until><( <{ y velocity }> <=> 0 )>
<change{ y velocity }by( -0.5
<end>

but for some reason this doesnt solve my problem

i have also tried:
<when green flag clicked>
<forever>
<if><key[ up arrow pressed ]pressed?>
<change{ y velocity }by( 0.2
<if><<  <not>  >><key[ up arrow pressed ]pressed?>
<repeat until><( <{ y velocity }> <=> 0 )>
<change{ y velocity }by( -0.5
<end>

but this hasnt worked either. please help!
