Clicking on the NPC won't start dialogue

Hmm, out of curiosity is there any reason why you are using Visionaire Studio 4.25? The latest version is 5.1.6.

In regards to the dialog not starting, I believe the action you have created an execute command at destination type action. Can your playable character reach the npc character/or the interaction position you specified on the npc properties tab? If they can't then the action won't be executed.

I didn't realise there was a new version available. I will check that out.

I think you might be on to something, but unfortuantely I"m extremely tired after working a long shift and just managed to really mess up my project. I'm going to restore a previous version and try again tomorrow. 

My controllable player was able to walk right up to the NPC, but your response reminded me that sometimes he would walk up to the NPC even when I wouldn't expect it (the npc is near the end of a waypoint). I'm going to try removing the waypoint and see what that does. When I click on the NPC maybe the player is just going to the end of the waypoint rather than to the NPC.

Thanks for taking the time to read my post and helping me.

  THANK YOU!!!!!

It worked!!!!
