Double Tap with UserInputService?
I'm trying to make a double jump script I know how to make the player jump twice but I do not know how to make it work by double tapping w :P
My attempt below V
1 | Input.InputBegan:connect(function(KeyInput) |
2 | if KeyInput.KeyCode == Enum.KeyCode.W then |
3 | Character.Humanoid.Jump = true |
4 | if KeyInput.KeyCode == Enum.KeyCode.W then |
5 | Character.Torso.Velocity = Vector3.new(0, 60, 0) |
6 | end |
7 | end |
8 | end) |
But that does not work :/ Can someone show me how to do this?
Thanks ~KiHeros

Your Problem
You're not thinking practically. You're thinking that by putting 2 if statements then it will check if they hit the button 2 times? It checks twice, if they hit the button. Not checks if they hit the button twice. Understand?
What You Need To Do
You need to take advantage of the tick function.
- tick function
returns the amount of time, in seconds, has passed since the epoch, or January 1, 1970.
By using this function you can get the time before the jump button was pressed, and after. If the difference between the two is less than a set time.. then activate a double jump.
Code
01 | --Last time the button was pressed |
02 | local lastTime = tick() |
03 |
04 | Input.InputBegan:connect(function(KeyInput) |
05 | --Check the keycode |
06 | if KeyInput.KeyCode == Enum.KeyCode.W then |
07 | --Get tick() time |
08 | local now = tick() |
09 | --compare tick()'s |
10 | local difference = (now - lastTime) |
11 | --Check if difference is less than a second |
12 | if difference <= 1 then |
13 | --if so, enable double jump |
14 | Character.Torso.Velocity = Vector3.new(0, 60, 0) |
15 | else |
16 | --Otherwise, normal jump. |
17 | Character.Humanoid.Jump = true |
18 | end |
19 | end |
20 | end) |
