Specific question about movement

[polyp]

Hello everyone,


I'm currently trying to make a very simple game where movement in one direction is done by pressing 2 keys alternately...

for example to move to the left, the user has to press A, S, A, S ... repeatedly (kind of like twiddling his fingers

and to move to the right, the user would have to press K, L, K, L repeatedly...


can anyone give me some insight on how this could be done?



thanks in advance

you would need to set up two boolean variables for each pair of buttons, then alternate their state when the button is pressed. in your handler you would use a condition to check if the button's variable is 'true' - if so, flip-flop the variables for the pair and then move the object slightly. so now if the user presses the same button again the condition will fail and not move the object nor swap the variable values.

thanks =)
