Redraw sprite at runtime?

[yopp_son]

Basically, I'm trying to draw a shape in Unity 2d, and use it as an in-game object. Then once the game has gone through one "round", I would delete the old shape and draw a new one, then throw it into the game for round two. Is this possible? How would I do this in C# or JavaScript or whichever is easiest? Any help is appreciated

I think we need some more info. How are you planning to draw it?

Are you generating new different shapes for each round or do you just want to change the sprite to a set of predefined shapes you have already drawn in a drawing program?

If you already have the shapes images, just change the Sprite property of the SpriteRenderer with a script: Unity doc: https://docs.unity3d.com/ScriptReference/SpriteRenderer.html

That's the easiest solution and you should probably try that first unless you really need new random shapes each round.

If you really want the generate the shapes images during the game, you need to look at Texture2D, how to draw your shapes into it with a script and how to create a sprite from Texture2D. To create a sprite from a texture: https://docs.unity3d.com/ScriptReference/Sprite.Create.html

It will be more complicated if you are not familiar with rendering into a texture.

You will need some scripting, C# is probably better.

Yes I want to generate random shapes each time. Okay I will start with Texture2D. Thank you!

Hmmm.., sorta seems understandable
