Workshop Matrix Demoscene

---

Goal is to achieve something like that

Implementation steps

Construction of matrix with: factory/matrix.go

File responsible to create the structure of the matrix, to create a letter object you will need to think about making it like a table.

1. Use function createNewLetterActor it will be required to give window/screen configuration and position coordinates where initially it will be placed in the screen.
2. To fill symbols like in the movie "The Matrix" take a look at function setSymbol it will randomly assign a symbol to your actor and that will be displayed on the screen.
3. Return slice of generated symbols/actors []entity.SceneObject from func CreateMatrix(...) it will be called in main.go for you.

Make effect of rain with: actor/letter.go

This file contains basic implementation on how it will behave during screen updates. Basically in method OnUpdate, you will try to reproduce effects from the movie "a rainfall of symbols". With structure MatrixLetter you have access to symbol MatrixLetter.Text.Position also you could access to the color MatrixLetter.color. So you could make movements of letters and color transitions during the update of the screen - each frame OnUpdate is called.

If simplify it, implement logic in OnUpdate method:

1. Symbol movement by updating MatrixLetter.Text.Position.
2. Symbol color transition by changing MatrixLetter.color.

Build

Before building by simple go build you need have SDL2 library with needed dependencies.

Debian and friends:

• apt install libsdl2{,-image,-ttf,-gfx}-dev

Darwin:

• brew install sdl2{,_image,_ttf,_gfx} pkg-config

When code will be compiled it may say about some deprecated warnings for Mac
