I recently entered the GBJam 11 game jam, and decided to give Godot a try for making my game, Space Walker. Here, I provide a summary of my thoughts on the experience of using Godot in comparison to using Urho3D/U3D.
What is needed to define a skill or technique or attack that a creature in a video game can do? Basically, a skill is a sequence of animations and movement to apply to the character at some cost, together with the (visual, sound, etc.) effects to produce, as well as info about the damage and statuses to inflict, and the hitbox over which it applies.
Starting in late spring 2020, I've been working on a procedural animation system. You can see a video from about 6 months into it here, at which point I thought it has reached a stage where it's nice enough to make a video showing it.
