-- 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
