These jetpacks are cool, but tricky things to control. Whats the “theory” behind them?
Here is what Mark from Dynamix had to say: The jet is just modeled as a constant force. When you press the jet key, it applies an acceleration of jetForce / mass (fields in armorData.cs). If you are not holding down a directional key, the force is applied straight up for maximum lift. If you are pressing a dir key, the force is almost completely applied in the desired direction, so you get a boost in the direction you want, but lose lift.
