Learning FreeBASIC through videogames

Hello everybody! Let's enrich our first code drawing four colored squares. This is the result of our new code: 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. Let me explain the new keywords used: line  to draw a line between a point referenced with its coordinates (value in axis x,value in axis y) and an increment/decrement in pixels form this point -step(inc/dec in axis x,inc/dec in axis y) and two parameters separated by comma, the first is the color and the second is optional, if you used it you can put a b that means box or bf that means box filled. Try changing color values from 0 (black or transparent) to 15 (white) and experiment with the parameters. This is e nough by now, in t he next entry we will make great advance learning a change in the structure of the code because the famous game loop. Contact me for any question,...

Come on everybody! Let's see our first code to make an screen to play. Let me explain the keywords used: '   t o add comments to the code, very useful to understand even the code made by ourselves. Used alone in a row or at the end of an instruction. const as integer to declare labels as integer numbers that contain constant values, non modifiable along the program. In this case w and h are constants. We must separate different consts with comma. screenres to do an screen to play, we have to tell two parameters the width and the height of the screen. We must separate parameters with comma. sleep to wait until a key is pressed to see the screen that otherwise will close too fast. end to end the program.  And the structure of this code not too far from the structure of a larger one: DESCRIPTION DECLARATIONS INITIALIZATIONS Main code ENDING In FBIde you can run the code pressing function key F5 or clicking Quick run icon This is the result of our ...
