19992000 Andreas Zehender &FDLNotice; 2003-09-17 1.1 &kspaceduel; is an space arcade game. Two ships fly around the sun and try to shoot eachother. Space duel KDE game ships shooting &kspaceduel; is an space arcade game for two players. Each player controls a ship that flies around the sun and tries to shoot at the other ship. You can play &kspaceduel; with another person, against the computer, or you can have the computer control both ships and play each other. The idea of the game is simple (but addictive). You try to destroy your opponent before he destroys you. Be careful not to hit the sun. Each player controls one ship. The ships can rotate, accelerate, shoot and lay mines. Each ship has an amount of energy (refer to the game options for values). Ships need energy for rotation, acceleration, shooting and laying mines. A ship gets energy from its solar panels. The amount of energy a ship gets depends on the distance from and direction to the sun. A ship gets more energy near the sun and less energy near the border. It gets the full amount of energy if the sun shines directly on the panels and less or even no energy if the sun shines at an angle to the panel or to the side of the panel. If a ship has no energy it can't navigate or shoot. Collisions with own or other bullets or mines decrease the hit points of a ship. If two ships collide, the weaker ship is destroyed and the hit points of the stronger ship are decreased by the hit points of the weaker ship plus an amount (Crash Damage). A ship is destroyed when it flies into the sun. Bullets fly around the sun like a ship. Mines have an amount of energy to stay at the same position. When the energy is spent, the mine falls into the sun. Mines near the sun need more energy than those which are further away. Mines can be destroyed with bullets. By default a ship can have 5 bullets and 3 mines on the screen. From time to time powerups appear on the play field. There are four different powerups: Mine The maximum number of mines is increased for the player. Bullet The maximum number of bullets is increased for the player. Energy (yellow sphere) The player gets energy. Shield (blue sphere) The player gets hit points &kspaceduel; Main Screen &kspaceduel; Main Screen You can see that the central part of the &kspaceduel; screen is the playing area. To the left and the right are the Red Player's and the Blue Player's stats. The top box on the player stats, represents the Hit Points of the craft. The middle box on the player stats, represents the battery power. The bottom box on the player stats, shows the number of wins. The top of the playing area is occupied by the menubar and toolbar. The bottom of the playing area is the status bar. &kspaceduel; has many, many options you can adjust to increase the enjoyment of this game. Configuration is divided into two sections: Player Keys Game Settings &kspaceduel; has a default set of keys to control the game. For a list of default keys see the section entitled Default key bindings. Keys can be configured by: Selecting SettingsConfigure Shortcuts... from the menubar. This will bring up a dialog box which lets you configure all hotkeys, including the keys used for steering the space ships, for firing bullets, and for laying mines. You can see that each player (Red and Blue), have 5 keystrokes corresponding to Rotate Left, Rotate Right, Accelerate, Shot, and Mines. When you are finished configuring your keys, you should click on OK to apply your changes. If you want to restore the default keys, simply click on the Default button once. To make these changes permenant, press OK. If you want to abandon the changes you made, and return to your previously selected keys, simply click Cancel, and your changes will be lost. All game settings of &kspaceduel; are configurable. If you want to change the game settings, simply select SettingsConfigure &kspaceduel;... from the menubar. This will bring up a dialog box with two pages, labelled General and Game. The first page is rather simple, the second one has seven tabs across the top. Settings are collected in different configurations. You can choose from several pre-defined configurations. If you choose the Custom configuration, you can define all settings for yourself. If you have not selected Custom, you will not be able to make any changes to these options. If you have found an interesting configuration, mail it to the author of the game. It can be implemented in a future version (send the part [Game] in the file ~/.trinity/share/config/kspaceduelrc). When you are finished altering the options, you should click on OK to apply your changes. If you want to restore the default, simply click on the Default button once. To make these changes permenant, press OK. If you want to abandon the changes you made, and return to your previous options, simply click Cancel, and your changes will be lost. The settings are: Hit Points These two sliders allow you to define the hitpoints for each of the two players; you might want to decrease the hitpoints for a player to give that player a handycap. Refresh time Time between two screen refreshes in milliseconds. All other settings are independent of the refresh time. Red Player Here you can define whether the red player gets controlled by the AI, and also choose the skill level of the AI for this player. Just experiment with the different skill level to find one which fits you. Blue Player This works the same as the options for the Red Player described above.
