I've written a very, very simple program to graphically display a problem (Inglenook Shunting Puzzle). It works fine, but I want it rerun upon a keypress. In other basics I would use something like WAITKEY. How can I do this in AGK

GetRawKeyPressed() is probably the command you want.

In the example below, it waits for the user to press Space (scancode 32).

For 'Any' key use GetRawLastKey()

But ...

So you must store the key and check if its changed

this might be closer to true WaitKey() ?

assuming the buffer was empty before calling? (i don't see a ClearBuffer() command but GetCharBuffer() clears it, so...)

That does negate the need of a variable, I like it.

Thank you all so much. V.Nomad solution worksfine.
Have moved onto recreating a racing game I wrote in Dark Basic about 20 yrs ago. New problem is how to make sprite background invisible. The background is black but Its still visible..

Quote: "GetCharBuffer()"

I don't remember having noticed that one before, which is surprising having such a small list of raw inputs, just always used key pressed/released/state or last key.

Triggering that on RETURN/ENTER key would be really handy for lots of things.
