Thank you soooooo much! This really helped! ❤️

Bite size training for big sized results. Love the content, keep it coming. Maybe throw out some ideas at the end of different things you can do with the same coding to get our imaginations going! Thank you!

Well explained sir

[@ayushsidam289]

That's great tutorial. But I have a question that can't we use components of cube gameobject directly using GetComponent(); without using tags. Please help!!!

[@hvm3164]

! SUPERB!

[@kiPROBRos]

Excelent tutorial, thank you very much. Big regards from Serbia!!! 👋👋👋

[@RootGames]

Thanks for the support!

[@gamesbyspinola]

on Get component without collision should we call on start or on awake ?? I see you call on start but I´d like to know if there is any diference in doing so as far the performance

[@RootGames]

For a modern PC, it really doesn't matter. Maybe for mobile it's better to use Awake more. In general, I combine Start and Awake, some things in the Awake that must be called before, and some things in the Start.

[@hvm3164]

the piece with "findGameObjectWithTag" made it click for me

[@vishnuppriyaj5886]

Can you please tell Is there a way to change some properties of other game objects by using GetComponent() in the same script . If so, How we can do that?

[@RootGames]

You can use tags to get component from the object you want, or you can just make public (or [SerializeField])variable and drag that component into the slot in the Inspector.

very nice

Thanks 🙂

[@venomradar]

How would i be able to use get component when i have two box colliders? How would i be able to distinguish between them? I couldnt find answers elsewhere please help

[@RootGames]

Then you need to use [SerializeField] and drag the specific collider you want to use.

[@theslinkbeast1086]

why we don't make instance of a class , like you made an spriterenderer object but you don't instantiate it by = new spriterenderer() line

[@RootGames]

Because I don't want to use a new spriterenderer component. I want to get the spriterenderer component that sits on the object.

[@theslinkbeast1086]

@@RootGames thanks for clearing my doubt

[@cattobean63]

Im a complete beginner, and I'm having trouble with the Transform component, why doesn't it show up as blue or any other color except white when I type it out????

[@RootGames]

Did you change the name of the script maybe? If not, Unity and Visual Studio lost connection. Go to Unity-> Edit -> Preferences -> External Tools Make sure that Visual Studio is selected as External script editor, and you can click on the "Regenerate project files" button.

[@suryaprakash9083]

Why get Component Lagging problem

[@RootGames]

If you use it correctly (not in the Update method) you will not have any problems, even on mobile.

[@thuanyeumh]

when i do this , my sprite was loss color ?

[@thuanyeumh]

[@testaqlk6173]

Hello... when you choose a new color from colorpicker, you need to change Alpha to 255 (default is 0).. this is the reason why your object "disappear"
