-- CONSTRUCTION MODE --
---------------------------------------------------------
A Hedgewars gameplay mode by mikade.
Special thanks to all who helped test and offered suggestions.
Additional thanks to sheepluva/nemo for adding some extra hooks.

---------------------
-- STRUCTURES LIST --
---------------------

* Healing Station: Heals hogs to 150 health
* Teleportation Node: Allows teleporting to any other teleporter nodes
* Bio-filter: Explodes enemy hogs
* Respawner: If you have one of these, any slain hogs are resurrected here
* Generator: Generates power (used to buy stuff)
* Support Station: Allows purchasing crates
* Construction Station: Allows purchasing girders, rubber, mines, sticky mines, barrels
* Reflector Shield: Reflect projectiles
* Weapon Filter: Removes all equipement of enemy hogs passing through this area

---------------------------------------------------------
-- SCRIPT PARAMETER
---------------------------------------------------------
The script parameter can be used to configure the energy
of the game. It is a comma-seperated list of key=value pairs, where each
key is a word and each value is an integer between 0 and 4294967295.

Possible keys:
* initialenergy:  Amount of energy that each team starts with (default: 550)
                  Note: Must be smaller than or equal to maxenergy
* energyperround: Amount of energy that each team gets per round (default: 50)
* maxenergy:      Maximum amount of energy each team can hold (default: 1000)
* cratesperround: Maximum number of crates you can place per round (default: 5)

For the previous 2 keys, you can use the value “inf” for an unlimited amount.

Example: “initialenergy=750, maxenergy=2000” starts thee game with 750 energy
         and sets the maximum energy to 2000.
Example: “craterperround=inf” disables the crate placement limit.

---------------------------------------------------------
-- Ideas list --
---------------------------------------------------------

* To make the weapon filter more attractive, make it vaporize flying saucers
  and also rope, and maybe incoming gears

* Make healing thing also cure poison?
* Maybe make poison more virulent and dangerous
