Adventure Creator - Make 3D adventure games (DEMO, VIDEO, WEBSITE)

Non-AC canvases should only interfere with Hotspots if "Unity UI blocks interaction and movement?" is checked in AC's Settings Manager. Otherwise, it may be down to your input settings or Hotspot-detection method.

Try it without a third-party asset, using the Demo game's Tin Pot prefab as the Player character to see if it runs using AC alone. Share details/screens over on the AC forum here.

 

Used this https://adventurecreator.org/forum/discussion/7440/hotspot-use-button-on-gui now hotspot work with canvas button, only i have to figure out why the scripts is not disable the on screen button. Although scripts has a condition to disable button when there is no hotspot. Will figure it out soon. Anyway thanks @ChrisIceBox

 

Ensure you're assigning the transform to the correct speech bubble object. Check if the speech bubble is a child of the NPC and that the assigned transform affects its position correctly.
