Check to see if a key is held down?

[bshennette]

How would one go about this?

For a game I'm making, I need to be able to make the character have 2 jump heights. What I had hoped to do was have pressing the key quickly be a small jump, and holding down the key be a large jump. Any form of checking to see if the key is held down would be fine.
If anyone could help me with this that would be great.

Turing:

%My Movement codes.         Input.KeyDown (chars)         if chars ('a') then             xv -= 1         elsif chars ('d') then             xv += 1         end if         if chars ('w') and ground = true then             yv += 10         end if

Please specify what version of Turing you are using
4.1.1

hmm... Well, I would use a counter. Have it start when the user clicks a key. When they let go, if the counter is within a certain range, perfom an action.

Why not use acceleration?

Pressing Jump at the start of a jump (when standing on ground), your acceleration is set.

While in air, the acceleration decreases (due to gravity). Holding onto jump would lessen gravity's effect, say a -=0.1 versus -=0.5 per frame.

I don't think a counter would work, because I can't use delays or else the rest of the program will stop running too.
Ill try Zren's idea.

Came up with my own idea:

Turing:

%Movement setup.         Input.KeyDown (chars)         if chars ('a') then             xv -= 1         elsif chars ('d') then             xv += 1         end if         if chars ('w') and ground = true then             yv += 5         end if         if chars ('w') and y2 < 100 then             yv += 1         end if

Just pressing makes a jump like 58, holding is 58<jump<140 depending on how long you hold it. (These are not accurately measured numbers, but rather approximations)

An interesting side effect is that if one continues to hold 'w' for the entire jump, the fall (below the height of 100) will slow down as well

It doesn't seem to noticably for me...
