I've seen people talking about invincibility frames or i-frames, for example, Dark Souls 2. What are they and what do they do?
Based on Smashpedia, invincibility frames are the period of time (measured in frames) during which a character cannot be damaged.
During the invincibility frames, most damage cannot be dealt to the character, and most invincibility will render the player invulnerable to disable as well.
Invincibility frame can be applied to game for skillful playing, like rolling/dodging, and special skills/items. It could also be added to prevent instant death upon respawning. Here are some examples:
- Dark Souls: Rolling
- Monster Hunter: Rolling
- Bastion: Rolling
- Guild Wars 2: Rolling
- DotA 2: Certain skills
- League of Legends: Certain skills and items
- Diablo 3: Certain skills
- Ikaruga: Respawning
- Gradius: Respawning
