ok... so... i am making a game... and i want it so that the person playing the game... has to type "start" in order to start the game
here is my code

+ Code Snippet

do
a = 2
if keystate(31) = 1 then CLS : Text 0,0,"'tart'"
if keystate(20) = 1 then CLS : Text 0,0,"'art'"
if keystate(30) = 1 then CLS : Text 0,0,"'rt'" : a = 1
if keystate(19) = 1 then CLS : Text 0,0,"'t'"
if keystate(20) = 1 and a = 1 then CLS : Text 0,0,"''"
loop

can someone fix this so that when i type in keystate(20) for the 2nd time... the text reads "''"... this is greatly appreciated... thanx

THANKS FOR STOPING AT A RED LIGHT... AND LETTING ME CRASH INTO YOU AT 80 MILES AN HOUR!!!

Hey hpfan,
I've seen your error in the code, and it's a common mistake. What you've done is reset the value of a to 2 each loop, in other words, you need to take a=2 out of the do..loop itteration.

The revised code is here:

+ Code Snippet

a = 2
do
if keystate(31) = 1 then CLS : Text 0,0,"'tart'"
if keystate(20) = 1 then CLS : Text 0,0,"'art'"
if keystate(30) = 1 then CLS : Text 0,0,"'rt'" : a = 1
if keystate(19) = 1 then CLS : Text 0,0,"'t'"
if keystate(20) = 1 and a = 1 then CLS : Text 0,0,"''"
loop

In your version of the code, by the time you've pressed keystate(30), and then pressed keystate(20), a has already reverted back to 2.

Hope it helps.
