Thanks brakeys that's what I need please keep doing videos like that

[ale-hlpg]

if anyone's confused by the method term
this was pretty confusing for myself as i switched from c

method = literally a function
method is used in java for functions inside a class, so he most likely got it off of that
member function is pretty much the same thing but it's used in c++ instead of method

on line 53 when you download pack and import script from in the 2d mega pack he forgot to put "yield return false;" he only put "return false" hope that fixes any errors!

Brackeys You can change the "New C# Script" template if you hardly ever use "System.Collections"

[blair]

I am getting the following errors

Assets/Standard Assets/2D/Scripts/EnemyAI.cs(13, 10): error CS0246: The type or namespace name `Seeker' could not be found. Are you missing an assembly reference?

Assets/Standard Assets/2D/Scripts/EnemyAI.cs(16, 9): error CS0246: The type or namespace name `Path' could not be found. Are you missing `System.IO' using directive?

Please tell me how to fix them.

[magnusm]

Wasn't Rigidbody preferred not to be used due to the many calculations it has to do and so it's better to just write it yourself to simplify it and less work?

[SmileyFaceMrlol]

What would you recommend to download if you wanted to make animations or texture an object on your own.

[jerrygreenest]

What about MVC in Unity?

...Btw what microphone do you use? :) Your site shut down so I can't read the FAQ (possible this question is there) :(

[Fanatator]

Uhm.
You were storing local rigidbody2d in a variable, misstyped a capital R and then said "It will give us a local rigidbody, and we don't want that"
That sounded weird a bit xD
Also I don't see what's the point in storing it, if rigidbody2d is the same thing..

[darkydrone]

What about enemies that they r on the ground?

[TheIndieGamesNL]

+Brackeys The Graph Lines are too big, is there a way to get more squares, andthus more precision?

[BlackTgaming]

Why do I get this error:
Assets/scripts/EnemyScript.cs(23, 22): error CS0103: The name `GetComponenet' does not exist in the current context

It highlights:

rb = GetComponenet<Rigidbody2D> ();

[gabrielvega]

please help I tried to use this script but every time I do it says "seeker cannot be found" along with path I even downloaded the script and used it and the same mistake came up what I think it is is its not importing the stuff from pathfinder when you do "using Pathfinding;" I'm kinda new to unity and c# so I tried everything i could think of i would appreciate your help thanks
