hi! i have a little problem. (idk if this is the right place to post this...)

how do i make something happen when i press a button repeatedly? (btw, im pretty good at scratch. So dont think i couldnt code anything by myself^^)

For example:

I want my character to bash when i press the left arrow key twice. How should i make that??

This is in the right topic! SmartIrishKid gave you the right code.

<if> <key[ left arrow ]pressed?>
(Code for Bash)
[/blocks]
The blocks didn't turn out right, but I hope that helps!

hmmm.. my game will be 2 players.. can is there no way to make every object have its own timer? or do i have to code it???

btw, it doesnt work! it will bash even if i hold the button... idk.. maybe im just stupid.. i didnt have much time to check it out really good.. i'll try again today.

You're not stupid, just inexperienced 

Here's something that might solve it well:

[blocks]<when[ left ]key pressed>
<repeat until><( <{ TIMER_VARIABLE }> <=> 1 )>
<wait until><not> <key[ left ]pressed?> >> --This could prevent a horrible glitch when holding the key
<if><< <key[ left ]pressed?> <and> <( <{ TIMER_VARIABLE }> <=> 0 )> >>
[insert bash script here]
<stop script>
<end>
<end>

<when[ left ]key pressed>
<set{ TIMER_VARIABLE }to( 0
<wait( 0.5 )secsc> --You can change this.
<set{ TIMER_VARIABLE }to( 1
[/blocks]

I hope that helped.

This script should work:
[blocks]<when[ left arrow ]key pressed>
<set{ key press valid? }to( 1
<wait until> <not> <key[ left arrow ]pressed?> >>
<repeat until> <( <{ key press valid? }> <=> 0 )>
<if> <key[ left arrow ]pressed?>
<wait until>   <not> <key[ left arrow ]pressed?> >>
.....[Bash script]
<wait until>   <not> <key[ left arrow ]pressed?> >>
<stop script>
<end>
<end>

<when[ left arrow ]key pressed>
<wait( 1 )secsc>
<set{ key press valid? }to( 0[/blocks]
