Well I'm sure there are other ways of doing it. I usually wake up from my sleep hours earlier because my subconscious tells me how to do things. (or god or whatever you wanna call it). Luckily I know a few ways that will work just fine with what I had in mind.
I'll just make a magenta colored version of a knife, blade, longsword, gun etc, then go to the sprites and draw the animations while making it "always set to image point X" and "always set animation to Player.AnimatinonName" along with "always set frame to Player.AnimationFrame"
I'm going to have to make a new item for each one being used, but luckily I'm doing a Castlevania style game play, so shield and sword will only be used in combat (and when idle if it's the last weapon you used).
And since I'm on the topic, is there any way of open sourcing this when I'm done so everyone can have a nice starting point to work with? I want to share this with others for rapid platform game development, but I don't know if my programming skills are good enough to ensure the fastest development experience. It's just a platform engine a la Castlevania (as I said) and not every animation is used, but can be implemented.
For example, I have many event sheets (five so far) for all his actions and animations, that way to keep organized without going crazy, but should I eventually put them all in one sheet and put them in groups to save on any headaches?
Sorry to sway so off topic there.
