Thanks, that's definitely better than what I have going on.  Just to clarify, will that really keep the arrow from pointing at the mouse cursor while in flight?  (My current model will turn sideways if I move the mouse.)

Also, I was imagining a system that fired one arrow per click, not that you have to hold down LMB, but hey.  Like I said it's way better than what I have.

Thanks

Yes, the arrow would stay pointing at it's target while in flight and not at your mouse. And since you want one shot per click, here's a somewhat-altered script that you could always use:

when gf clicked
forever
 go to [Main Sprite v]
 point towards [Mouse Pointer v]
 if (mouse down?)
  repeat until <(touching [bad guy v]?) or (touching [edge v]?)>
   move (20) steps
  end
  wait until <not (mouse down?)>//This is what causes the 1 shot per click.
 end

Well, the blue [change y by] block is under Motion, and the others you should find by going to Variables, then to "Make a Variable", then typing in "Y Velocity", and finally hitting "Okay"

I hope that this helps!

Hi, I've been on Scratch for over 3 years now and I was wondering if I could become a member. I'm not a master programmer, but I could definitely be of help, especially to the New Scratchers. Thanks 

I'd like to sign up to help with scripts.

Hi,
Hoping someone may be able to point me in the right direction.
I have a .txt file with a string of numbers in, I want to create a script that will read through the string and then move onto the next line.

I have been able to read and extract the data from the string ok, but I can not seem to be able to move to the next line in the .txt file

Any help appreciated

Ohhh... This problem sounds interesting. How exatcly are you reading the .txt file? Are you saving it in a variable and then reading it?

The only way I could think of would be to get each digit of the .txt file to be a variable and have a list of these variables for each line.

I am making a game with lives so I made a varibal called lives and made it so that when the green flag is clicked they set to 3 and if you touch the enemy you lose a life. But I can't figure out how to make it game over when you have lost all 3 lives. Does anyone know how to?   

when gf clicked
forever if <(lives)=(0)> //or lives is smaller than 1
broadcast [game over v]
end
end

Wanna know how to make a wall jumping game? Well it's right here!

when gf clicked
set [R-vel v] to [0]
set [L-vel v] to [0]
forever
if <key [right arrow v] pressed?>
change [R-vel v] by (1)
end
if <key [left arrow v] pressed?>
change [L-vel v] by (1)
end
if <key [up arrow v] pressed?>
if <color [#0000FF] is touching [#000000]?>
set [Y-vel v] to [20]
broadcast [Jump v]
end
end
if <not <color [#0000FF] is touching [#000000]?>>
change y by (-5)
end
if <color [#FF0000] is touching [#000000]?>
set [Y-vel v] to [0]
set [R-vel v] to [0]
if <not < <color [#0000FF] is touching [#000000]?> or <key [up arrow v] pressed?> > >
wait (0.5) secs
if <key [up arrow v] pressed?>
set [Y-vel v] to [20]
broadcast [Jump v]
end
set [L-vel v] to [10]
end
end
if <color [#00FF00] is touching [#000000]?>
set [Y-vel v] to [0]
set [R-vel v] to [0]
if <not < <color [#0000FF] is touching [#000000]?> or <key [up arrow v] pressed?> > >
wait (0.5) secs
if <key [up arrow v] pressed?>
set [Y-vel v] to [20]
broadcast [Jump v]
end
set [R-vel v] to [10]
end
end
change x by (R-vel)
change x by ((0) - (L-vel))
change [R-vel v] by ((R-vel) * (-0.2))
change [L-vel v] by ((L-vel) * (-0.2))
when I receive [Jump v]
repeat (10)
if <color [#FF0000] is touching [#000000]?>
set [Y-vel v] to [0]
stop script
end
change y by (Y-vel)
change [Y-vel v] by (-1)
end
set [Y-vel v] to [0]
