Auria {l Wrote}:sorry, I don't think there is a way at this time to make a speed boost without the effects to go with it. That could be a feature request but I can't tell you when it could be ready given how small a team we are
I don't have time to test atm, but setting speed-gain to 0 should do the trick. Again, please read data/stk_config.xml:
- {l Code}: {l Select All Code}
<!-- time is the time a zipper is active. force is the additional
zipper force. speed-gain is the one time additional speed.
max-speed-increase is the additional speed allowed on top
of the kart-specific maximum kart speed. Fade-out time determines
how long it takes for a zipper to fade out (after 'time'). -->
<zipper time="3.5" force="250.0" speed-gain="4.5" max-speed-increase="15"
fade-out-time="1.0" />
Speed-gain is the one time instant speed boost you get. If you set this to 0, only the increased force will work, which will (slowly) accelerate the kart.
Cheers,
