Object Rotations

Man, I did some maths since I started this project !! I’ve got 3 papers on my desk filled with matrix and calculations… There is nothing really hard though.

I added rotations to my objects. It also means if an object rotates it’ll rotate its children. I just need to save rotations in my timeline and add a blend between two key frames and then I should be able to make this skeleton move :

(Red  arrow : local X axis ; Green arrow : local Y axis)

With such an animation editor I should be able to do complex animations with bones and scripted animations (such as falling objects without physic…).

I should be done with this part of the editor soon. Then I’ll work on the FX ! It should be cool.

To sum up, right now I have :

– Hierarchy
– Animation
– Collision detection
– Collision map creation
– Objects creation/edition
– Level editor
– Serialization

Enough to start a game I think… without sound and FX (shaders I mean… Since I could use animations).
But I’ll try to make my editor as complete as possible till end of march. I’ll start after that. Can’t wait ! 🙂

I’ll try to do some videos soon (while working on the FX).

I’m almost done with refactoring (some parts are still horrible though). But the code looks cleaner !

I stopped my refactoring to add a little feature to the editor (and engine) : hierarchy. You can now attach an object to another one if they should be moving together and so on (Father node moves its childs).

Example :

Right now I’m working on the rotations. Then, using my animation timeline, hierarchy and rotation, I wonder if I will be able to make something like an animated stick-man. Well, I should…

PS : the sprites used in my tests are made in photoshop with brushes found here and there on the Internet. I’m not the creator and I won’t be using those brushes in any game.
