Currently it just switches up by one hero.

To change, I had to change the set_status rpc protocol to include
rotation (that way switching heroes isn't jarring); so they're combined
here.

Hero 0: Remove cursor, allow wallriding (enable collision detection)

Hero 2: Move RepelHUD to center, ignore self with Area (gravity)

I didn't know you can do this. It's really, really nice! I can change
properties, hide, and add, to the player scene.

Accidentally put it in the wrong place before

Within radius 8, attracts heroes with gravity.

When it's too short, the scrollbar makes it completely illegible

Also add variation in spawn point, so that all spawns are not on top of
each other

At this point I've pretty much deleted all of Calinou's code. Oh well,
it DID get me started.

This prevents hero 1 from permanently setting the objective to one side,
making them very OP and the game un-fun.

Any object with collision mask=2 will no longer collide with the
objective.

In multiplayer, if there is only one hero 1, it is ok, but with more
than one, one hero 1 cannot place walls.

Just to make my git clean

I messed up the last commit by not including a file, this fixes that.

Changing the weight of the objective fixes the weird destroy-the-player
physics.

Also, count how long the objective has been tilted to the right or left,
and put counters there. Slow the game down and display who won when the
count exceeds 100% on either side. Like in overwatch, but with tilting.

This reverts commit 22cf954991.

While on wall, if you press jump, you leap up and away from the wall

If you do so immediately after leaving the wall (<tolerance=.150s), it
still works

Unfortunately, apply_impulse seems to have no effect right now. More
research is needed.

There however were some bugs that came with this, so I'm switching to
master to explore this.

The camera setting got changed to default-enabled, when it should be
default-disabled.

That is, even if there are less than MAX_PLAYERS
