So I was reading the VEX manual and I was confused about what the phrase, "directly or indirectly meant
Here’s the rule for reference
Park Zones are protected during the endgame. During the last 20 seconds of a Match,
Robots may not directly or indirectly contact the other Alliance’s Park Zone or opponent Robots that are
Parked in that Zone.
Does “indirectly” mean with blocks or is there another meaning?
Most likely it would mean with blocks that is the only meaning I think it means unless there talking about touching the bot
yup, not allowed to use game object as a glove, or other robots, or generate an earthquake that causes robots to get hit with a tsunami wave knocking it out of the parking zone and into spectator stands!
Yes. According to rule , generating tsunamis and earthquakes to force a robot out of the park zone and out of the field is strictly prohibited 
But if I’m being honest, I would think that if students could generate an earthquake with the right amount of precision and force to knock a robot out of the park zone, I feel GDC would allow it, just because of how much precision it would take 
Could also mean ramming the perimeter with the intent of upsetting a pair of balanced robots.
In most instances like this, the word “indirectly” could be read as “transitively”
I think it is desiged to limit the use of tactical nukes as they can indirectly vaporize the parking zone, thereby deleting the endgame from existance and presenting numerous challenges for the next match including, but not limited to: radiation, craters, seismic shocks, lack of field, lack of building, lack of town, etc.
