Flying is an action that can occurs when Mario triple jumps or does a cannon shot while wearing the wing cap.
Entering flying
- Cannon shot: when y vel < 0 (and Mario does not cancel) (Action argument: 0)
- Flying Triple Jump: when y vel < 4 (and Mario does not cancel, dive, or ground pound) (Action argument: 1)
- Spawning in, e.g, Tower of the Wing Cap: (Action argument: 2)
Behavior
As with all airborne actions, a variety of "cancels" are checked prior to actually performing any airborne action. See Jump#Airborne cancels.
Then:
- If Z is pressed
- If Mario's camera mode is CAMERA_MODE_BEHIND_MARIO, set_camera_mode to m->area->camera->defMode
- Ground Pound
- If Mario is not wearing the wing cap
- If Mario's camera mode is CAMERA_MODE_BEHIND_MARIO, set_camera_mode to m->area->camera->defMode
- Freefall
- If Mario's camera mode is not CAMERA_MODE_BEHIND_MARIO, set_camera_mode to CAMERA_MODE_BEHIND_MARIO
- If the action state is 0
- If the action argument is 0 (was shot from cannon), set Mario's animation to MARIO_ANIM_FLY_FROM_CANNON, else set Mario's animation to MARIO_ANIM_FORWARD_SPINNING_FLIP
- If the animation finished,
- If the action argument is 2 (spawned in), load_level_init_text and set action argument to 1
- Set Mario's animation to MARIO_ANIM_WING_CAP_FLY
- Set action state to 1
- Call
update_flying
- switch Movement_steps#Perform_Air_Step:
- air step none:
- Update graphics (camera) angle to be behind Mario
- Set action timer to 0
- air step land:
- Set action to Dive Slide
- Set animation to MARIO_ANIM_DIVE
- Set animation frame to 7
- Set facing angle (x) to 0
- Set camera mode to m->area->camera->defMode
- air step hit wall:
- todo
- if wall is not null, stuff, Backwards Air Kb
- else, stuff (but no knockback, this is probably out of bounds)
- air step hit lava wall:
- stop holding, stop riding, Lava Boost
- air step none:
- finally, play the flying sound (adjust sound for speed)
