Spikes that protrude/retract on a timer

[GreyMario]

Trigger spikes but they activate on time instead of movement (Ex: standing on them will kill you if you don't jump right away) also they deactivate after a couple of seconds

A similar idea to Trigger Spikes, except on a timed cycle.

Personal notes: I like the idea of being able to define "active" and "inactive" durations, as well as a time offset, so that they can be used to create a sequence of safe and unsafe spots. Additionally helpful would be a short period of time when they look like trigger spikes to warn the player that they're about to pop out.

Another user expressed interest in this idea. Let's keep it around and bang it out, it might still see use.

I'll see if I can make something like hollow knight's timer spikes, with an active time, inactive time, and an offset so you can alternate them.
