+`while true` is an infinite loop. It ends only with the `break` command or when the script is ended (e.g. using `terminate_this_script`).
+
+It is often used to create a main body of a CLEO script, which contantly awaits for a key press to trigger some action.
+
+```
+while true
+    wait 0
+    if
+        is_key_pressed 113 // F2
+    then
+        break
+    end
+
+    add_score {player} 0 {money} 10
+end
+terminate_this_script
+```
+
+This loop adds $1 to the player's account each frame until the F2 button is pressed to exit the loop. Note that after breaking from the loop, the script continues to the next command, which is `terminate_this_script`.

-Many things in the game are extended in time or depend on the player feedback. A car driving to a destination, a model file loading from the disk, a button awaiting to be pressed all require a specific condition to become true. Did the car reached the point, was the specific button pressed, is the model available for use? If not, wait and check again later.

 We can validate certain condition continuosly, each frame, or with some delay. To achieve this in the code, a special construct exists: a loop.
