simple drawing question

[mike_g]

hi ive just started with glbasic on the gp2x. going nicely so far


ive chopped together some code. here it is:

// --------------------------------- //
// Project: Keyboardtypography
// Start: Monday, April 30, 2007
// IDE Version: 4.104


main_loop:
count1 = 0
count2 = 0
count3 = 0
LOADSPRITE "line.bmp", 0
WHILE TRUE // Endless-Loop (can use the counts to change the RGB values based on how many times the key has been pressed previously)

      DRAWLINE 100, 100, 110, 120, RGB(0, 0, 255); // Cyan

    IF KEY(57) = 1; PRINT "CLICKER is Pressed", 100, 100;

     DRAWLINE 100, 200, 150, 10, RGB(100, count1, count1);
     count1 = count1 +1;
     IF count1 >= 254 THEN count1 = 0;
     PRINT count1, 200, 200;
     ENDIF;
       IF KEY(30) = 1; PRINT "A is Pressed", 120, 100;
      FILLRECT 9,    50,    39,    80,    RGB(100, count2, count2) ;
     count2 = count2 +1;
     IF count2 >= 254 THEN count2 = 0;
     PRINT count2, 200, 220;
ENDIF;
IF KEY(32) = 1; PRINT "B is Pressed", 120, 100;
      FILLRECT 40,    50,    70,    80,    RGB(100, count3, count3) ;
     
     count3 = count3 +1;
     IF count3 >= 254 THEN count3 = 0;
     PRINT count3, 200, 230;
ENDIF;
    SHOWSCREEN
WEND
SHOWSCREEN
GOTO main_loop

///END of code


---basically what i want to do now is to draw a circle the same size as the square on the first keypress in the same place as the square. it would need to stay there after the key has been pressed also.

for each consectutive keypress i need a single line linking up each position of square .
and the line would also need to stay until clearscreen as with the circle.

any ideas?

regards
mike

cheers for the circle code whoever did it BTW
P.S if i was to get the new breakout cradle and plugged in a usb keyboard would glbasic accept input from it?

Not yet. Should be easy to implement, though.

[mike_g]

thanks ill take my chances and get a cradle over the weekend.

any ideas about the previous line drawing question? this would now apply to the centre of the circles drawn. ie. how to draw lines from each in the right order and line color which stay on the screen until i tell it to clear?



regards

If you want something to stay, then remember it in a variable, and draw it for every SHOWSCREEN.
