(III) Make an screen to play: ', const as integer, screenres, sleep & end

Come on everybody!


 Let's see our first code to make an screen to play.
Let me explain the keywords used:
  • ' to 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 first code:
An screen to play with 400 pixels of width and 300 pixels of height.

 This is enough by now, in the next entry we will enrich our first code drawing some squares.

Contact me for any question, see you!

(II) Download & setup FreeBASIC's IDE FBIde

Hi everybody! If you use Microsoft Windows on your computer you can download FBIde from SourceForge in this link:  https://sourceforge.net/projects/fbide/files/ Go to fbide 0.4 folder and then fbide 0.4.6 r4  folder and download the zip file with the name  FBIde0.4.6r4.zip . Note: 0.4.6 r4 is the last version while doing this blog entry. Now decompress downloaded file in the path you desire. Me I decided to use my Desktop, beside my FreeBASIC compiler and help folders. Go into  FBIde0.4.6r4  folder and execute the application  fbide Click Yes in the message window. And search fbc application inside your FreeBASIC's compiler folder to open it. Go to View/Settings to Choose your Theme for the editor, I like obsidian theme. Add some new Keywords in Group 2 . Choose the path for FreeBASIC Help file (.chm) downloaded in the previous entry of this blog. Remember to click OK to submit the changes. This is e nough by now, i...

(X) Writing in the screen: draw string, locate & print

How everybody! In this entry we will see how to write in the screen, to know for exemple how to show things like information or our score. Take a look at this code: We have already seen drwa string but l et me explain the new keyword used: locate  to drive the cursor used by print to the desired position in the screen. print to print a value in the screen. When we execute this code we can see this: locate and print works together and understand the screen like tiles of 8x8 pixels where there's only place for a character (1,2,3,...,a,b,c,d,e,...,!"·$%&/..., etc) in each tile, starting at 1,1 position whre the fist number is the value of the row and the second value the column that's why the second message appears at the second row and starts at the fist column. The colors used are the default (black/white) or the one's selected by the color instruction that we talk about in the past entry. This is e nough by now, i...
