[How to make it 2d scrolling game in project vertigo?]

@Lumiere,  Your video is lagging right ? It makes it look like the animations are choppy.
                  Though, it looks like a good project you have there. :)

[[Eo 3.0] DoubleExp by NPC for x hours]

The topic title explains it all.
Is there any custom script that could enable 2x exp when the correct item is in
the inventory ? 
Example ;    Player possess 2x exp coupon for 2 hours -> Give item to NPC =
                                                        Having 2x exp for 2 hours.

Thank you,
Attila.
