SDL and Key Trapping

[BastetFurry]

This goes as follow:

Code:

dim keys as uint8 ptr  
keys = SDL_GetKeyState(NULL)

if keys[SDLK_UP] then
  ' Do something
endif
if keys[SDLK_DOWN] then
  ' Do something
endif
if keys[SDLK_LEFT] then
  ' Do something
endif
if keys[SDLK_RIGHT] then
  ' Do something
endif

Problem here is that you cannot do it with a nice looking select but have to use if´s as keys is an array of 255 elements.

If you need to know what SDLK_Something you need have a look at SDL_keysym.bi

Have fun ^.^

EDIT: If you just want to check it when a key is actauly pressed, check your event holder for SDL_KEYDOWN

(Just copied my simple keywait routine)

Code:

sub SDL_WaitForKeypress()
   dim WaitForKeyEvent as SDL_Event
   do
   SDL_PollEvent(@WaitForKeyEvent)
  
   select case WaitForKeyEvent.type
      case SDL_KEYDOWN:
         'Do your key stuff here!
         exit do
      case SDL_MOUSEDOWN:
         'Do your mouse stuff here
         exit do
   end select

   loop
end sub
