Easy! have separate key down events that have stuff like

Code: Select all

y = y - 1;

then the next one would be like

Code: Select all

y = y - 2

but on for the second key down event put "wait for frame action" use one of your animations and put 1; then the third put 2; etc.[/code]

then put the revers of all that on a key up event.

Is better use something like this:

Code: Select all

directional_velocity *= .5;

Oh, i guess that could work too.
