Help with the error "an explicit conversion exists (are you missing a cast )"

Questions & Answers

I’m currently working on a game tutorial from UnityCookie. CG Cookie | Learn Blender, Online Tutorials and Help - CG Cookie | Learn Blender, Online Tutorials and Feedback

Around 28:40 is where we add some new code that is confusing to me for convert from JS to C#.
In the “else if” statement, we add code to access another script. The script name is LandingPad.cs. Im not sure if i’ve intrepreted the JS to C# correctly there. Reason why i think this is the line “landingPad = hitInfo.gameObject.GetComponent(“LandingPad”);” is giving me this error “an explicit conversion exists (are you missing a cast )” I don’t understand what that means. Any help is much appreciated. Thank you.

landingPad = hitInfo.gameObject.GetComponent(“LandingPad”);

will return just a type of component, you need to use the generic and it will return the correct type… type of LandingPad instead of type of Component.

landingPad = hitInfo.gameObject.GetComponent<LandingPad>();

or if just incase, here is the cast to LandingPad from Component.

landingPad = (LandingPad)hitInfo.gameObject.GetComponent("LandingPad");
