How to do a Bejeweled Gem Shine Effect?
When the gems are idle in a game of Bejeweled they like to do a shine (or reflect?) effect. Is that something that must be animated on the art side or is it possible to use a shader to generate this effect?
Yep, it's a sprite and I think you're absolutely right. Just following this YouTube video on Photoshop (I'm not an artist!) I was able to get an effect that I'm happy with.
Thanks for the info about the 3D model side too. I was thinking of trying it if this didn't look right.
You can repost this as an answer.
If you're using sprites, then it should be done on the art side, and merely have your script for the jewel trigger the shine animation after delta.time has reached a certain threshold, and reset the counter when that happens or if it's interacted with.
If it's a 3D model, then you could use a shader that has specular and merely increase it's value like you would trigger an animation in the previous method. Though this effect wouldn't look that great unless you had a good enough model and lighting setup, preferably an environment map for the shader. All depends on the look you're going for.
+1. I'd like to add on to this answer, you could also use a particle system w/ a sparkle material and proper settings for a shimmering effect.
