How can I activate a GameObject Component of type script?
Hello community.
I'm trying to access an script as component inside a GameObject.
This is the code:
Component playerSpawnScript = _scriptContainer.GetComponent(typeof(PlayersSpawn));
But when I try to set it to Active, I don't see any property or method that let me do it.
I'm with .NET 4.6 experimental.
Regards!
PlayersSpawn playerSpawnScript = _scriptContainer.GetComponent<PlayersSpawn>();
playerSpawnScript.enabled = true ;
Hellium showed the preferred and usual way to access script components. However if you want / need to use a System.Type parameter for some reason you can do
void SetScriptEnabled(System.Type aType, bool aState)
{
$$anonymous$$onoBehaviour inst = ($$anonymous$$onoBehaviour)GetComponent(aType);
inst.enabled = aState;
}
Note that the base class Component doesn't have the concept of "being enabled". The Behaviour class (which is derived from Component and the base class for $$anonymous$$onoBehaviour) introduces the enabled property. Therefore every script you write has an enabled property. Note that some built-in components of Unity also have an enabled property but are not derived from Behaviour. So their enabled property is a completely seperate property and can't be treated in an abstract way.
Though "scripts" (aka classes derived from $$anonymous$$onoBehaviour) all have a common enabled property due to their common ancestor (Behaviour).
@Ryujose the Component class doesn't have an "enabled" property, this is why you can't enable it (strictly speaking we activate/deactivate GameObjects and enable/disable scripts):
https://docs.unity3d.com/ScriptReference/Component.html
An OOP refresher:
Since your PlayersSpawn script -apparently- derives from $$anonymous$$onoBehaviour, which derives from Behaviour, which derives from Component, you can actually assign the PlayersSpawn script to a variable of type Component per your code, i.e. all PlayersSpawn types are also Component types.
However, it's not only that a Component doesn't have an enabled property, but since you declare the playerSpawnScript to be of Component type, you won't be able to access any of its members e.g. its variables and methods. In other words, playerSpawnScript in your code, can only function as a Component and not as a fully fledged playerSpawnScript.
The most general (least derived) Unity class which inherits from the Component class, and has an "enabled" property is Behaviour:
https://docs.unity3d.com/ScriptReference/Behaviour.html
However, if you don't just want to enable/disable, but fully functioning playerSpawnScript you should follow what @Hellium said in his answer.
It would also be very beneficial for you to do some scripting tutorials:
public GameObject gameObjectWhichHasTheScriptAttached;
//write this where you want to disable the script
gameObjectWhichHasTheScriptAttached.GetComponent<nameOfScript>().enabled = false;
