 # How do I make a timer?
 
 Raylib has no built in timer system. You are expected to keep track of time in your own code. You can do with with the GetTime and GetFrameTime functions. Below is an example of a simple timer struct and functions to use it.

 The Camera2d structure is used by `BeginMode2d/EndMode2d` to define a 2d transformation. This is very useful for games that want to draw a 2d world in a fixed coordinate system and have the ability to pan, zoom and rotate the view without the need to change drawing code.
 
 ## Fields

 typedef struct Camera2D {
     Vector2 offset;         // Camera offset (displacement from target)

 Raylib does not offer any text formatting functions, so you need to compute the starting point for all text that you draw. The starting point for text is always the upper left corner.
 
 You can compute the center of the screen by dividing the screen width and hieght in half.
-```
+```c
 int screenCenterX = GetScreenWidth() / 2;
 int screenCenterY = GetScreenHeight() / 2;
 ```
 Next you need to compute how large the text is, and offset the center by half the text size.
 
-```
+```c
 const char* text = "Congrats! You created your first window!";
 
 int fontSize = 20;
