CEDEC2026 Session Explains the Theory Behind Convincing Fighting Game Action
The session gives fighting game designers a concrete vocabulary, phase fusion, kinetic chain, and energy escape, for making over-the-top moves read as convincing rather than weightless, and it grounds that vocabulary in live Chinese martial arts demonstration rather than abstract theory.
Key Facts
- CEDEC2026 ran July 22 to 24, 2026 at Pacifico Yokohama North.
- Ishiguro and Sato argued that convincing action builds on a base of real movement rooted in physics, anatomy, and kinesiology, with acting and exaggeration layered on top.
- The session proposed sketching weapon tip trajectories as a starting point for designing continuous attack sequences.

A CEDEC2026 session, held July 22 to 24 at Pacifico Yokohama North, argued that convincing fighting game action starts from a base of real movement rooted in physics, anatomy, and kinesiology, with acting layered on top and exaggeration added last. The talk, titled "Continuous Attack Action and Multi-Person Fighting Action Animation Design Recipe ~With Chinese Martial Arts Demonstration~," featured Masataka Ishiguro, who handled game design and motion design for early Tekken and Soulcalibur titles, and Taichi Sato, head of the Enbukan martial arts school. The two introduced phase fusion, the smooth connection of preparatory, main, and terminal phases of a motion, and the kinetic chain, the flow of energy through muscles and joints. They noted that deliberately breaking the kinetic chain can express character, such as throwing a punch before the body follows to suggest mastery, or delaying the punch to read as a brawler. For exaggeration, the key is where energy escapes, like a horizontal sword slash that swings so far behind the body that one hand leaves the grip. The session also proposed sketching weapon tip trajectories as a starting point for designing continuous attack sequences.
The session framed attack mechanics around three keywords: mass projection and reaction, instability, and instantaneous rigidity from muscle coordination. Ishiguro noted that impact effects shown at the moment of a strike are a staging lie, since the energy is actually delivered in the phase before the pose, and that exaggeration only works when the energy has somewhere to go. A horizontal sword slash, for example, can swing so far behind the body that one hand leaves the grip while staying real.
For heavy weapons, the weight has to be considered. A spear is swung by pulling its center of gravity toward the body's axis and pushing off the ground, and a zhanmadao is drawn in, lifted on momentum, and brought down with gravity, ending in a low stance. The session also covered multi-enemy fights, including turning a dodged attack into a backfist, using a grabbed opponent as a human shield, and pinning one enemy while striking another.
Ishiguro proposed sketching the trajectory of a weapon tip as a way to generate action ideas, then filling in weight shifts and opponent reactions. The session closed with the point that exaggeration only works when the real movement underneath is understood first.
