Learning FreeBASIC through videogames

Howdy everybody! Take a look at the new code of the day: In this code we have defined new keyboard scan codes for the arrow keys, see it in the DECLARATIONS as constants and declare variables to control if the keys are pressed or not, like we did it with key escape. Here x and y that are the coordinates of the white square will turn into variables because we will move this square then the value of the coordinates will be variable. When we DO UPDATE this time we will check also the four possible arrow keys and checking not to go with our white square outside our screen, otherwise the square will hide, you can prove it. Notice that the condition is multiple, using and to check that both conditions are true at the same time to change the value of the corresponding variable. We increment or decrement x or y with 1 (1 pixel), to go up y-1, right x+1, down y+1 or left x-1. This way: To increment we use the form variable+=amount of increment, for exemple x+=1 To de...

Hey everybody! Take a look at the code of the day: The result of execute our new code will be the same as the obtained with the code of the last entry but you must press Esc key to exit: An screen to play with 400 pixels of width and 300 pixels of height and four squares of 32x32 pixels one in each corner. The white square is painted or filled with same color. The screen is being draw again and again and again until you press Esc key. Let me explain the new keywords used: dim as boolean  as const as but with dim we are telling that the label (in our case finish and kescape) will have a variable value. In the case of boolean this value can be false or true. do loop until to make a loop that will repeat the code inside the instruction until the condition after until is resolve to true. if then else  to execute the code inside the instruction if the condition is resolve to true, else to execute an alternate code if the condition is  not resolve to true...
