User Customized Input
« on: November 29, 2020, 12:37:58 pm »
We see a lot of people post little games around here.  We also see a lot of other people post things like "Can you change it so that I can use XXX key for (whatever), rather than what you have set?"

Here's the very simplest set of code I can think of to allow someone to set custom controls for a game:
Code: QB64: [Select]
  1. PRINT "Press the key you want to move UP   :";
  2. Up = SetKey: PRINT Up
  3. PRINT "Press the key you want to move LEFT :";
  4. Left = SetKey: PRINT Left
  5. PRINT "Press the key you want to move DOWN :";
  6. Down = SetKey: PRINT Down
  7. PRINT "Press the key you want to move RIGHT:";
  8. Right = SetKey: PRINT Right
  9.  
  10. HeroX = 20: HeroY = 20
  11.     CLS
  12.     LOCATE HeroY, HeroX: PRINT CHR$(1);
  13.     K = _KEYHIT
  14.     SELECT CASE K
  15.         CASE Up: HeroY = HeroY - 1 - (HeroY <= 1)
  16.         CASE Left: HeroX = HeroX - 1 - (HeroX <= 1)
  17.         CASE Down: HeroY = HeroY + 1 + (HeroY >= 25)
  18.         CASE Right: HeroX = HeroX + 1 + (HeroX >= 80)
  19.     END SELECT
  20.     _LIMIT 30
  21.     _DISPLAY
  22.  
  23.  
  24. FUNCTION SetKey
  25.     STATIC KeysInUse(1 TO 100) AS LONG
  26.     DO
  27.         SetKey = _KEYHIT
  28.         FOR i = 1 TO 100
  29.             IF KeysInUse(i) = SetKey THEN SetKey = 0 'Can't define the same key twice.
  30.             IF KeysInUse(i) = 0 THEN EXIT FOR
  31.         NEXT
  32.         IF i < 101 THEN KeysInUse(i) = SetKey
  33.         _LIMIT 30
  34.     LOOP UNTIL SetKey > 0
  35.  
  36.  

It really can be that simple of a process.  :)

I like this. Some games, namely Portal 2 and Rage to name a few, ask you to "look up" right off the bat, so whatever your natural reflex is, that's "up" for now on, and so on. This is right in that spirit.
You're not done when it works, you're done when it's right.

And here's a version which looks more like what my game has going for it:
