Toggle Boolean by Input.getKey like if pressed one time true next time false and so on.
Hello All,
I want a Toggle Boolean by using Input.getKey(i don't want it by keydown) like if pressed one time true next time false and so on. I have tried the code but it gives weird result. here is the code.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class NewBehaviourScript : MonoBehaviour
{
public bool suri;
void Update()
{
if(Input.GetKey(KeyCode.A))
{
suri=toggle(suri);
}
}
public static bool toggle(bool suri)
{
return !suri;
}
}
GetKey returns true every frame while the key is pressed.
Why don't you want to use GetKeyDown or GetKeyUp which return true only the frame when the key goes down / goes up respectively?
Thank you for your reply.
@Babish8 and @Hellium i am working on physical joystick which don't have button up function. It only have boolean, which onpress become true else false.
I want to have a toggle function on that button. so i cant use GetKeydown.
@AhmedElshazly i have tried this but it changes too fast and sometime don't work.
try adding a delay and make sure you're not using static variables
I haven't tried the following code
public class NewBehaviourScript : MonoBehaviour
{
public bool suri;
private bool isPressingKey;
private bool IsPressingKey
{
get { return isPressingKey; }
set
{
if(value == isPressingKey)
return;
isPressingKey = value;
// isSuri will be toggled when the key gets pressed down
// if you want the boolean to be toggles when the key is released
// change the condition to `if(!isPressingKey)`
if(isPressingKey)
suri = !suri;
}
}
void Update()
{
IsPressingKey = Input.GetKey(KeyCode.A);
}
}
However, it's tedious. Maybe the new Input System could solve your issue in a more elegant way.
This doesn't work on my setup it's still giving issues of randomly true or false. Like I have have pressed one time and it quickly goes through true true and some time skip false and vice versa.
I needed something like event or state. I think but no idea how to use it.
Well, this just manually emulates pretty much same behaviour as
if (Input.GetKeyDown(KeyCode.A))
suri = !suri;
The only difference would be when you use that inside FixedUpdate you get a different behaviour. So your code is essentially a GetKeyDown variant that works properly in FixedUpdate. Though in the original question he has the code in Update so this snippet works exactly like GetKeyDown as I shown above.
However since the actual goal is still unclear we essentially running circles here. The OP should clarify the question. Currently the question is not really clear and detailed.
Indeed @Bunny83, the code I wrote tends to copy the behaviour of Input.GetKeyDown. This is what I understood from OP's question since he/she can't use Input.GetKeyDown directly but still wants the same behaviour.
@suri44 I don't really get the problem you are facing. The script I've provided works as follow:
Default value of
suriisfalseWhen pressing down the
Akey,suriturns totrueand remains totrueas long as you hold the keyWhen release the
Akey,surikeeps itstruevalueWhen pressing down the
Akey again,surichanges tofalse. Releasing the key does not change the value ofsuriWhen pressing
Aa third time,suriis changed totrue
Try Using this if(Input.GetKey(KeyCode.A)) { suri = !suri; }
Here is my '5 cents'
BTW I'm not sure but I guess that if you use only GetKey (instead of GetKeyDown) it will keep calling the code inside untill you hold the key. so try it with GetKeyDown instead
public bool isActive = false;
private void Update()
{
if(input.GetKey(KeyCode.A))
{
isActive = !isActive;
//more code here
}
}
This will toggle the boolean every frame while the key is pressed.
well what else did you expected?
The OP wants with GetKey. I made an edit and mentioned about that.
Plus from persona experience I can't see anothe way to use Input.GetKey methods elsewhere except Update methods and Triggers
Thanks Everyone, for all the solutions.
@Hellium you are right, your solution works special thanks to you.
