Keycode discrepancy

Blitz3D Forums/Blitz3D Programming/Keycode discrepancy

The scancode chart/picker in Blitz3D claims that the backspace key is 14 ... however, in practice, my keyboard reports a value of 8. This worries me.

Is there some way to account for these differences?

Try this code on your machine...

While Not key
	key = GetKey()
Wend

Text 0,0,key
WaitKey


If I run this and hit backspace, it will report 8. Hold me.

well none of them seem to work wiht that code. key 'm' should be 50 but it reports 109.

8 for me. In any case, the return value of GetKey is an ASCII code, not a scan code.

14 is indeed the Backspace key for my keyboard.

Try this code:
Time = MilliSecs()
While Not KeyHit(1)
	Time = Time + 8
	Repeat
	Until MilliSecs() > Time
	Text 2,2,"KeyDown(14) returned "+KeyDown(14)
	Flip
	Cls
Wend


You will also encounter real differences in scancodes.
They are based on the physical layout of the keys.

The values listed in the Blitz docs are for US/UK keyboards.

In any case, the return value of GetKey is an ASCII code, not a scan code.

True. I'm a dumb ass.

Stop holding me now, it's getting weird.

Peh. That's nothing. I once spent an hour wondering why a variable wasn't coming up as 5. The code was x=7-1. I swear to God.

I once put

if t=s\target_handle
s\ship_handle=t
endif

and wondered why my ship behaved oddly.
