What should be the C# syntax for the condition if (This Button is interactable)?
I have a script attached to the button, Which has to run only if the button is interactable.
Thank you in advance!

Once you have reference to a Button, you can use Button.interactable to determine if the button is interactable. interactable is a member of the UI.Selectable class; Button inherits from Selectable, and thus, has access to interactable.
The below script takes a Button reference, and runs logic if the button is selectable. When you intend to "run the script", simply call Run(). The logic will not run, if the Button is not interactable.
public Button button;
public void Awake()
{
if(button == null)
{
button = GetComponent<Button>();
}
}
public void Run()
{
if(button != null && button.interactable)
{
// run your logic, here.
}
}

Checking button.interactable checks only if the button itself is interactable, completely ignoring the possible existence of Canvas Groups.
The correct check should use IsInteractable() instead of interactable:
public Button button;
public void Awake()
{
if(button == null)
{
button = GetComponent<Button>();
}
}
public void Run()
{
if (button != null && button.IsInteractable())
{
// run your logic here.
}
}

\$\begingroup\$ This seems wrong. Your first part of the condition does not make much sense. And while
IsInteractable()is a nicer way to access the bool, it still seems to go as well to check againstinteractable\$\endgroup\$Zibelas– Zibelas2024-02-28 16:45:29 +00:00Commented Feb 28, 2024 at 16:45 -
\$\begingroup\$ According to the code, it also checks
m_GroupsAllowInteraction\$\endgroup\$2024-02-28 18:25:09 +00:00Commented Feb 28, 2024 at 18:25 -
\$\begingroup\$ @Zibelas it is not a nicer way of acessing the bool. That is the point. This function and the property test for totally different things (which is omitted in Unity documentation). The bool tests if this selectable's flag is set to true while the method checks if the selectable overall is interactable (taking into account parents that may have Canvas Group with disabled interaction). \$\endgroup\$Parchandri– Parchandri2024-02-28 20:22:09 +00:00Commented Feb 28, 2024 at 20:22

\$\begingroup\$ But than that should be explained in your answer why it should check for a canvas group (and not just as a comment) \$\endgroup\$Zibelas– Zibelas2024-02-28 20:59:40 +00:00Commented Feb 28, 2024 at 20:59

\$\begingroup\$ @Zibelas It does say in his question "Checking button.interactable checks only if the button itself is interactable, completely ignoring the possible existance of Canvas Groups. The correct check should use IsInteractable() instead of interactable" \$\endgroup\$Pow– Pow2024-02-29 00:49:59 +00:00Commented Feb 29, 2024 at 0:49
