GetKey Problems

[Zen]

Hello. If i put a 1 as the parameter for GetKey it doesnt return the virtual code (i dont think) or at least i couldnt get it to work. It just returned the letter i pressed but in uppercase

That would be the virtual key code. 

The list : (should look familiar)

Codes are OR'd together for things like the shift and control keys.

thats what i thought, i assumed it would be the same as INKEY$ in IBasic. but a-z just prints out A-Z and nothing for return or backspace. same as the F keys, F1 starts at p and works its way along the alphabet and F12 prints a {

Im sure there must be something goin on.

here is some exampel code to show you what i mean.

Code Select Expand


global sub main() {

int end = false;
string input = "";

do {

input = getkey(1);

if(input = "Q") { // Should be 51 not Q as it should return the virtual code

end = true;

} else {

writeln(input);

}

} until(end = true);

return 0;

}

Q in ASCII  = 51.  You can't treat the return as a character when using the 'raw' method.  Use the ASC function.

[Ionic Wind Support Team]

You could also use

if input[0] = 51

If you don't want to use the ASCII funciton.

Thanks Paul. I will take a look tomorrow.
