So I'm making an RPG. In one of the places its night And I'm wondering how I could make a barrel animated with fire emit a pulsating glow around it. I parallaxed the map in Photoshop (like I've been doing with all my maps) with a black layer given a light opacity to create the illusion of night. I was thinking of adding in the glow effect in Photoshop but I'm not sure how I would animate it. Plus that might be real tedious. Can I animate it in game maker some how. A step by step walking through of this would be helpfull or a video walkthrogh. I learn best through follwoing pre set out examples.
