i need help dont know what is wrong

[bluesniped]

it says something like component contains no definition for enabled.
i want this script to activate another script at a certain point.
thanks for help

Welcome to the forums. Please post as text in code tags, not as a screenshot. The code tags button looks like this on the toolbar in the text area where you type in your post: </>.

Recall that C# is a case sensitive language. Enabled is not the same as enabled. Perhaps you meant to use the former?

Ok, thanks good to know i will do it like that next time.
eitherway it will not accept the enabled and gives me error codes -->

Compiler Error CS1061​

 

[Skydiver]

That is because according to the documentation, GameObject.GetComponent(string) returns an object of type Component. Also according to the documentation, Component does not expose any property named enabled (or Enabled). So the error returned by the compiler is right on the money.

You will have to downcast that returned object to a type that does expose enabled. Or use the variant of GameObject.GetComponent<T>() that will return an object of the requested type T.

Is there a good way that i can script the "CarController" script to get active after the racing countdown? because it does not work like i thought, maybe in java script? but unity removed them.
but there has to be another solution but i have massive problems with getting the right idea. i dont think that i can downcast it because the carcontroller is the carcontroller is cannot change much there, and i dont think that the type T will get it to work

 

[Skydiver]

The T is the type parameter, by convention in C#. So you would write something like: Car control.GetComponent<CarController>().enabled = true;

I have no idea if that will do what you desire. That assumes that your CarController class or one of its bases classes has an enabled property.

How much C# programming have you done prior to jumping into game programming in Unity? It is usually a good idea to learn the programming language first, before trying to learn how to use a game engine/framework. If you are trying to learn both at the same time, you make two moderately steep learning curves into a single very very steep learning curve.

 

[bluesniped]

"enabled is a method group, so an assignment is not possible" even with your version of it.
i really new to c# im learning by doing, i have some tutorials that help me through the stuff but that is the first problem i face becuase the exact same code is working for others...
i have no clue thats why im asking here, its motivating me to see the progress i make while the codes are useful for my own game. better then just watching tutorials for me and i get some experience

 

[Skydiver]

Show us the code for your CarController for us to be sure, but that new error you are getting suggests that you have declared enabled as a method like this:

class CarController
{
    :
    public void enabled(bool enable)
    {
        :
    }
    :
}

instead of as a property:

class CarController
{
    :
    public bool enabled
    {
        set
        {
            :
        }
    }
    :
}

With an enabled method, you need to pass in a parameter that value of true or false. With an enabled property, you need to assign true or false to it.

// setting a property
carController.enabled = true;

vs.

// calling a method passing in a parameter
carController.enabled(true);

i managed to get it working in unity 2017 (first version) i feel like that version is better for beginners i used the help of javascripts which had no errors at all, i think i will stick with the older version first now until i get some more experience?
but if you want you can still try to solve it for the future but thanks for your advices here

 

[alexhortdog95]

So - just looking at your initial screenshot, did you try .Enabled instead of .enabled? C# is a strongly typed language and as such, it is picky about casing.
