Hey, guys! I've made a habit of posting here lately. Hah

So, as I'm plugging away at my game here, I've run into another snag. I'm not so great at transforming models. I can do basic stuff like simple positioning, or opening/closing a door or drawer, but when it comes to actual fluid natural movement, I'm a little stumped.

If anyone could give me a tip, some method that would make moving models a little easier than, say, setting the position for every frame of the animations I'd like, that would be wonderful. =]

This bit seems tricky.

Thanks a lot!

Screenshot for reference:

If the hilt of your sword is positioned at the origin then you could simply rotate it on the x/y axis (the one along the sword edge) to achieve a simple swinging effect.  Just have a swing rotation variable that you increase until it is at 90 degrees or so and then have it decrease back to zero.  You could also use a timeline to move the model every step (not just rotation but transformation also) which could also become a full blown animation system which would come in handy later in the dev process (for enemies and other AI).

I s'pose it would come in handy. It would just be extremely difficult to work with is all. Hah

Might I add that the screenshot you have reminds me of Minecraft. Is that the kind of game you are trying to design?

The best method I can think of would be the use of circular functions, such as Sine or Cosine. It provides for smoothness in the swing (as opposed to a fixed speed down and then up)

You can implement it by setting the angle of the sword equal to the result of a sine function, multiplied by the angle you want to swing at, consider:

The y value shown by the curve between 0 and pi is what you want to apply to your angle. (Any further than pi and you will smack yourself in the face)

I hope it is helpful and easy to comprehend ><

I realize that is looks a lot like Minecraft. I'd actually come up with this idea before I knew Minecraft existed, and just haven't made any progress on it until lately.
It's not based on Minecraft in any way, it's just due to the graphical limitations of Game Maker. There's no way I'm putting any high-resolution images on cubes. xD

Thank you very much! This helps a lot! It's gotten rid of my frustration.
It's a pretty decent way to do things, for now at least. I think at some point I'm going to add in my own animation engine as earlier suggested, which will ultimately replace this way, but I will still credit you for sure.
