Hello Engineers!

I was look at Types/Animation and Types/Sprite hoping to find a way to make existing Animations and Sprites transparent (or more transparent).

I noticed that both Animations and Sprites have:

• apply_runtime_tint
• blend_mode
• premul_alpha

Given their similarities, I would hope these Animations and Sprites properties are treated identically as far as modders are concerned.

I assumed by their name/documentation that there should be some type of runtime/boot-up process of increasing (decreasing?) Animations and Sprites alpha values (to make them more transparent; reduce opacity). Is this wishful thinking? Or would I need to create new image files for every Animations or Sprites that I want to make (more) transparent? I've tried every combinations of things to try to get this working without luck. Apparently my graphic lingo isn't strong enough.

I also noticed Types/SpriteFlags used by both Animations and Sprites, but I'm not sure which flag(s) I would use to apply a transparency change.

Thanks ,

Dude, I feel like at this point I have kicked around every color/alpha value in this game, and I still don't quite know how they all layer. In your case I think you should try the runtime tint first. Set r, g, and b to whatever, then the a value to your desired transparency. See what happens. I got that to work once with player mask colors on a vehicle (since vehicles apply player colors as runtime tints): if the player had alpha less than 1, it made the vehicle transparent. Generally speaking I would start with altering the animation value for whatever prototype you're messing with, and hope that you can find a way to do it there, because I've had only mediocre success doing much with the other values.
