how would I put together a blue print mechanism that scores player action according to time?
for instance an onscreen prompt says turn left and if the player turns left immediately they get 5 points and this score goes down one point for every second later until 5 seconds where they get no points at all?
You can use Get Game Time in Seconds to get the current game time as soon as the prompt message is displayed. Then when the player reacts to it (input event), you call it again and calculate the reaction time as the difference between the two. Provided the player went the right way, you can assign Points = 5 - reaction time.
Cheers,
Marco.
What would that look like as a bp?
