these two functions will convert a scancode to the actual key name (as a string ) and vice versa.



Mouseclick() detects when the mouse is pressed in.I made two functions which tell you when the mouse or any key was pressed out, ie. released.Some may find this useful since mouseout() or keyout() can't happen continually like mouseclick() for example you have a menu and when you click a button and it goes to the next screen and there is a new button at the same location,if you use mouseclick() it will detect it and will act as if you pressed the second button too.There are a few other uses.

the first function was designed to allow the programmer the freedom of not having to peek at that every now and then... but its up to you ,whatever rocks your boat

A study done by William Speyer, who was a victim of prison rape in 1989, shows that 34% of [prison] rape victims released from prison become child molestors.

For other options, here is all the codes encoded as various constants. They are very easy to use. Example: Just use "ks" in place of "keystate(31)" for the "s" key.

Quote: "CHR$

This command will return a character string equivalent to the ASCII character number provided. ASCII is a standard way of coding the characters used to construct strings. The value provided should be an integer value.

Syntax

Return String=CHR$(Value)"

Quote: "ASC

This command will return an integer value that represents the ASCII code for the first character of the provided string.

Syntax

Return Integer=ASC(String)"

If speed is an issue, you would not use a function to convert scancode to key names - you'd load all of the names into a 255 item array, and just index that directly.

Converting key names back to scancodes (can't think of a reason why you would ...) can be made fast by storing the names and their values in an array sorted by name, and using a binary search on the array. For 256 values, that would give you 8 or less comparisons to find any one of the values.

thanks for the feedback! did you try the mouse/keyout functions?

Try this,
it makes a button (clicked once even if you keep pressing it)
and it makes a statement for the button (on or off states, can be easily increased)

this reminds me:

in a game im making i'd like to convert asc to scancode values.
is it possible?

this is the code i use:



this is for the "customizable controls" thingie.
in previous versions of the game, i created something along the lines as the first post in this thread, but it was too much of code.

i'm using DBC.
