Title: "Brightness Slider" for QBASIC and QB64.
Post by: MarkSkits on June 11, 2018, 10:15:43 pm

Note: Uses QBMOUSE Sub

Code: QB64: [Select]

1. SCREEN 12
2. startPos = 50
3. endPos = 590
4. currentPos = startPos
5. colorValue = 9
6. COLOR colorValue
7. LINE (50, 239)-(590, 241), colorValue, BF
8. LINE (startPos - 1, 230)-(startPos + 1, 250), colorValue, BF
9. MOUSE 1
10. Text$ = "Current Background Brightness:" + STR$(FIX(Brightness)) + "."
11. LOCATE 13, 40 - (LEN(Text$) / 2)
12. PRINT Text$
13. LOCATE 13, (40 + (LEN(Text$) / 2)) - 3
14. PRINT RTRIM$(STR$(FIX(Brightness))); ". "
15. DO
16.     MOUSE 3
17.     SELECT CASE B
18.         CASE 1
19.             IF H >= startPos AND H <= endPos AND V >= 230 AND V <= 250 THEN
20.                 DO WHILE B = 1
21.                     MOUSE 3
22.                     IF H >= startPos AND H <= endPos THEN

38. LOOP
39. SUB MOUSE (Funk)
40.     SHARED B, H, V
41.     STATIC Crsr
42.     IF Funk = 1 THEN Crsr = 1
43.     IF Funk = 2 AND Crsr = 0 THEN EXIT SUB
44.     IF Funk = 2 AND Crsr = 1 THEN: Crsr = 0
45.     POKE 100, 184: POKE 101, Funk: POKE 102, 0
46.     POKE 103, 205: POKE 104, 51: POKE 105, 137
47.     POKE 106, 30: POKE 107, 170: POKE 108, 10

50.     POKE 115, 204: POKE 116, 12: POKE 117, 203
51.     CALL ABSOLUTE(100)
52.     B = PEEK(&HAAA)
53.     H2 = PEEK(&HBBC)
54.     H2 = H2 * 256

Hi! I wonder why you don't use QB64's inbuilt mouse command. Using them will make your work easy.

I made it so it would work with QB64 AND QBasic.
