canGateGlitch (Hard)

The ability to open a left-facing blue or green gate from the right, using Missiles or Supers. The generally applicable method to do this is to stand some distance away from the gate, hold angle-up, jump, press and hold forward, then frame-perfectly fire a shot just before Samus would bonk the gate.

It is recommended to stand 2 pixels away from the gate. From this position, the shot will always clip through the gate as long as shot is pressed 2 frames after forward. This remains true regardless of whether Samus is in air or underwater physics. The height at which the shot is fired does not matter, as long as it is high enough to not pass under the switch on the other side of the gate. The shot can be fired either before or after Samus bonks the ceiling, but there is an advantage to waiting until after bonking, because 1) this puts the shot closer to the center of the frame window that works, and 2) it allows the player to focus on the critical timing, which is between the forward and shot press, without being distracted by the jump.

Dev note: Standing 0 or 1 pixels from the gate never works. Standing 3 pixels away, some subpixels fail to work at all. Standing 4 pixels away, the required timing between forward and shot depends on subpixels. Standing 5 pixels away, some subpixels fail to work at all. A number of tries can't be applied as leniency within this tech's requirements, because the resource cost is not included in the tech (it varies with circumstances). There is a helper for each combination of circumstances, and it's recommended to apply a number of tries as leniency on all such helpers that use this tech.
