Images / Sprites

Game screen images, UI, buttons, and other misc. images are located in the /img folder.

All of the help screens are located in the /img/help folder.

The game sprites (ships, selections, hits, and destroyed stations) are located in the /img/sprites folder.

The power up icons (def, tec, spd, wep) are located in the /img/sprites/icons folder.

Note that buttons are included in the graphics. A transparent PNG is placed and sized for the button sprite in the code.

Also, note that the game board is a single image.

The PSD files for all images are located in the /img/_PSD folder

Javascript

This game uses the Phaser HTML5 Game Framework.

All of the Javascript files are located in the /js folder.

shipsPerTick - How many resources can fit in a single ship, per tick.

shipCombat - A toggle to enable/disable ship to ship combat.

mothershipStart - Resources the mothership starts with.

ufoStart - Resources the ufos start with.

earthStart - Resources Earth starts with.

stationStart - Resources the stations start with.

spawnRate - Base player spawn rate, per tick.

enemySpawnRate - Base enemy spawn rate, per tick.

spawnBonus - A multiplier for spawn bonus (i.e., the more resources you have, the faster they'll grow).

speedStart - Base player ship speed (per frame)

enemySpeed - Base enemy ship speed (per frame)

maxUpgrade - ! This value is pretty much hard-coded into the game, since there only graphics to accomodate this many levels !

defCost - The costs for def upgrades

tecCost - The costs for tec upgrades

wepCost - The costs for wep upgrades

spdCost - The costs for spd upgrades

tecBonus - The spawn bonus given for tec upgrades (added to spawnRate)

aiPlans - An object containing some enemy AI settings:

• random_attack_freq - Out of 100, whether or not to randomly attack per tick
• aggressive - If true, the mothership will aggressively attack Earth when a station is destroyed
• mass_attack - A toggle for the mass attack plan (mothership will build up a single UFO, and unleash a large attack)
• limit_break - A toggle for the UFO "limit break", which increases its speed and spawn rate (only increases once per game)
