Key checking

SDL Development
1

Is there a way I can tell if a key (any key) has been pressed without
looping through all the events?

I have a GUI event handler, but I don’t want to ‘suck’ all the events out
because I check for keys being pressed at different locations in the code
during a single loop._________________________________________________________________

what i do is i keep an array of the key states, then when i need to check a
keypress, i check the array. When i process the events, i take keydown
messages and set the keys to down and keyup sets the keys to up…> ----- Original Message -----

You should seriously consider restructuring your code so that you don’t
do that. It will cause problem after problem after problem. My guess is
that you could solve the code by rewriting sections as state machines
with a very small number of states.
