How do I make multiple sequence key commands?

Hello everyone,

I searched the forums but could not find a suitable answer for this: how do I implement multiple sequence keys commands, like in SF2's Hadouken (down, down+front, front - punch)?

Is there any tutorial I may have missed? Any tips/help?

Thanks in advance,

Marcelo

Hi thealchemistbr - Let's take the "down, down+front, front, punch" example:

Set up a string global variable to store sequence of keys pressed - initial value "".

On key press "down" set variable to "down,"

On key press "down+front" if variable is already "down" then change to "down, down+front" else (whatever appropriate)

On key press "front" if variable is already "down, down+front" then change to "down, down+front, front" else (whatever appropriate)

On key press "punch" if variable is already "down, down+front, front" then do the SF2 Hadouken thing else (whatever appropriate)

If you have many such multi-key commands than you might want to plan a matrix of these before coding them up.

Hope that helps.

Sure it does. Just thinking - how would I properly determine is the first down should put the player to down animation or start the sequence? Maybe a tick-based flag?

You could try including a time element, like if they don't press the second key within so many ticks you just do the down animation and reset the variable to "".

Will try that approach. Thanks a lot!

No problem - let me know how you get on.
