I want to create an animation, but when I drag my sprites(Flat images) in the animation window, it doesn't allow me to drop them.
So, I can't make an animation, which is needed to make a game.
I am a noob, so forgive me if the answer is obvious.

The question is a little too vague, but what you will need to do to animate a sprite, you will need to first add it in your scene and then you will be able to animate them. If you're using sprite sheets however This official tutorial should help

Check if you have clicked on the game object that you want to create an animation yet.

So the problem is the following:
I have been trying to make this flying simulator little phone game, the problem is i cant make the shadow change with a smooth transition...
That White squared is a cloud, and the objective is to have the shadow change size while in the cloud...
I don´t really know were to start, i tried shaders, but i´m not that good with that...
Thx :))
If you are not into shaders, I would look into Masks. Masks basically limit a sprite to only draw within it's boundaries.
In this example, you could have a mask on the cloud. To make it work, have the "nearer" shadow be always drawn, but only in the mask's boundaries (In this case - the cloud) Relevant Youtube Tutorial

I'm trying to make this aiming projectile for one of my games and wondering what is the best approach to achieve this. I want the motion aiming projectile with moving dots towards the pointing direction.
Thanks in advance!
You can use a LineRenderer for this purpose.
You can achieve the dotted line effect by supplying the LineRenderer with a dotted line texture and tiling it for a continuous dotted line effect.

I am new to SceneKit, currently playing around with it.
I use 4 boxes as walls to create a sort of skybox.
Each box/wall has its own starfield texture. Currently this causes the borders of the walls to be visible. I want to remove these line borders, any idea?
That is a result of the texture you use, which is not seamless. Look into "seamless tileable" textures. A much better approach to do what you are trying to do however, is to use the scene’s background property as explained in the answer of this question: How to set contents of scenekit background to cube map

I created a border of black patches and the rest of the "walls" of the maze are purple. How would I code the maze so that it won't walk into the walls? And also how would you code the up/down/left/right buttons to control the turtle that walks through the maze. Thanks so much! I tried so much but I can't seem to get it to work.
I think you will find everything you need in this example model in NetLogo Model library
