You can use inkey for letters..

Ie..

if upper$(inkey$()) = "W"
move object up 1,1
endif

for example.

Sure can

numbers will work this way...

Do something like..

if inkey$() = "7"
print "hello"
endif

Also consider scancode and keystate. These commands are your friends for keyboard input.

Adding on to what phil said, the values for the keys can be found here. You would then use them as follows:





both of these examples would return a one if "w" is pressed. Hope this helps

I think that should be
If scancode()=17 then ...


The word "Gullible" cannot be found in any English Dictionary.

A good tip for beginners is that when programming complex games its sensible to have a function which checks the keystate of each key each loop and then saves the result in a variable. You then check the value in the variable using an if/then to decide what action to take later. This saves more than one check of the keyboard state each game loop.

This is how I do it

#CONSTANT up = 118
#CONSTANT down = 119

#CONSTANT True = 1
#CONSTANT False = 0

IF KEYSTATE(up) = True

I like KEYSTATE, because you can have multiple keys held down at one time and it doesn't freak like INKEY$() would.

I also assign True and False, to 1 and 0, because it's easier to remember that way and it's a neater layout when your looking through mountains of code.

Oh ya, and Up and Down may not have the right numbers assigned to them, because I can't remember what they are off hand..

I usually have another program handy for checking scancodes.. the program is as follows..

SYNC ON
HIDE MOUSE

DO
CLS
PRINT SCANCODE()
FASTSYNC
LOOP
