GetKey is too fast.

I'm having a tough time trying to make this work.

I have a top down game where you use the numpad to move the guy around the screen tile to tile.

Initially I used GetKeyDown, and that worked great if you just wanted to hit the key a million times to walk down that corridor.

So I tried GetKey which repeats, but it's way too fast. Just tapping numpad 6 makes the guy move about 5 squares to the right with the slightest touch. I'd like the key repeat to mimmick the system key repeat if possible. Is this possible?

My movement code is basically like this in C#:

void Update () {

//
// Move Right
//
if (Input.GetKey("[6]"){
stuff
}
}

How can I slow the key repeat down, but not limit it to a single key?

 

can you post the movement code; are you multiplying with deltaTime?

 

To directly answer the question you could do something this

bool foo;

if(Input.GetKey("[6]") foo == true){
foo = !foo;
//Stuff
}
Else if (foo == false){
foo == !foo;
}



^^ that would cut the amount of times your code is executed in half similarly you could iterate an int and reset to 0 each time the code executes if you need to be able to slow it down more than half.

There is likely a better way to do what you are looking for though than slowing down the execution of Input.GetKey.

 

I am just translating a sprite from one point to another. Think of it as a roguelike. Every 64 pixels per move. You can hold down the 6 key and the guy runs down the hall as fast as your system has its key repeat set at. With Unity, it updates every frame using Update() so it's much too fast.

I'm not sure setting a variable or doing a loop would help, it would be different for every machine then. I was hoping there was something built into unity that would just set it to system, or maybe a way to define input.getkey rate. Maybe an Update method that fires every 1/25th of a second?

 

set up a repeating timer, something like

Code (csharp):

1.  
2. float lastStep, timeBetweenSteps = 0.5f;
3.  
4. if(getkey...){
5.   if(Time.time - lastStep > timeBetweenSteps){
6.     lastStep = Time.time;
7.     //Do step
8.   }
9. }
10.  

will execute the step every 0.5 seconds

 

Here's some sample code to get you started. Basically you want to keep track of the amount of time that has passed since the last frame, add it to a variable that keeps track of total time and then if the total time passed is greater than or equal to the customizable key delay then act accordingly. I hope this helps.

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class KeyTest : MonoBehaviour {
6.  
7.     public float keyDelay = 1f;  // 1 second
8.     private float timePassed = 0f;
9.    
10.     // Update is called once per frame
11.     void Update () {
12.         timePassed += Time.deltaTime;
13.  
14.         if (Input.GetKey(KeyCode.Space)  timePassed >= keyDelay) {
15.             // do stuff
16.             timePassed = 0f;
17.         }
18.     }
19. }
20.  

 

Changing input rate is not what you want. If this is some sort of grid movement, then you simply have movement continue as long as the key is held down, and stop otherwise. See demo here and code here.

Thanks for the suggestions! Checking them out now.

It appears the timer suggestions seem to have a lower limit of around 0.5f .. if I change it to 0.25f or even 0.002f the delay is still .5 seconds. This is for both examples.

Eric5h5, your example is better, but it is not precise. It is like the input is being buffered. In the demo, try and stop precisely at a predetermined point. More often than not, you will overshoot.

Edit:

The timer methods work, I noticed over in the Unity GUI the delay was still showing the older values and not updating properly. Restarting Unity fixed it.... The timer methods are exactly what I wanted. 0.1f is the perfect delay I was looking for!

THANKS!

 

I use on key up for the keyboard overrides (although this is only for the testing, so not sure how it will work in a production, mines touch screen primarily)

 

That's only because of the default Unity settings for the Horizontal and Vertical axes, which have smoothing built-in, where it takes a second for the input to go back to 0. So I bumped the gravity and sensitivity to 99 and re-uploaded.

This piece of code work just fine to slow down all your input:
...
private float presedShiftInTime = 0; // Counter time for pressed button
...
public float slowButonsPressed = 3; // magick number to "slow motion"

void Player_Run()
{

if(Input.GetKey(KeyCode.LeftShift))
{

presedShiftInTime += Time.deltaTime*10;
if(presedShiftInTime > slowButonsPressed)
{

player_Animator.SetBool("Run", true);​

}
else
{

player_Animator.SetBool("Run", false);​

}​

}
else if(Input.GetKeyUp(KeyCode.LeftShift))
{

presedShiftInTime = 0;
player_Animator.SetBool("Run", false);​

}​

}
