In qbasic, you could type a$ = input$(1)
so the user can input a variable without any prompt on the screen. How can I do this in dark basic?

thanks

I don't know of any commands like that build-in to DBP. However, I wrote a quick function to do it. Not quite the same, but works anyway.

Function:

I'm not sure you understand completely. All I want to do is have a user be able to input a variable, without anything on the screen. As in, the screen can be blank, and also waiting for him to input, without a ? or a whatever the blinking line that shows where ur text will appear is called. You need to do this in many games, like in a 3d game W goes forward, it doesnt give a cursor and yo press W and enter, u press W once and W is inputed.

You need to use scan code(). There is an image somewhere with all the keys and there scan codes, hopefully a helpfull person will post it.
Use this code to print the scan codes to the screen

The scan code for the w key is 17 so in your code you would have.
do
if scancode() = 17
do what ever it is you want to do when the w key is pressed.
endif
loop

You know Chris, this isn't QBASIC. DB is much more powerful. You can use commands like Upkey(), Downkey(), etc. or scancode like the_winch said. Those commands are much faster than my input routine.

i know this is thread is bout a week old....but i had finally made my own snippet of code that does exactly what your ask....no prompt....the text type out as you type it and your still free to do what ever else you want...no program freezing while it waits for you to type your input

now in my code it uses a 800x600 screen and types out the text on the bottom 5 lines of the screen....and scrolls it up....now in mine you have to press enter for it to scroll up.....from the way you described that this is more what you want....but maybe not....let me know what you think....

this was a code i wrote to get rid of the cursor and use the back space to clear
hit enter to leave/save just like the input command

works pretty much like the input command except you can have other things goin on in the loop (i had the mouse selecting things)


(the screen will be blank till ya type something)

My advice is free -
unfortunately you get what you pay for (-:
