Both teams are able to build structures such as spawn points, which are vital to their victory. The goal of Tremulous is to eliminate the opposing team and all of their spawn points. \layout Standard Each team in Tremulous differs fundamentally from the other. The aliens are class based, with two classes initially available: the alien team's builder, known as the Granger, and the Dretch, the weakest offensive alien. The aliens are awarded frags for killing their foes which may be used to evolve into stronger classes, capable of greater and more varied maneuvers. In contrast the human team is upgrade based, receiving credits for kills that may be exchanged at an Armoury structure for new weapons, armour and equipment. Two such upgrades are available for free: a rifle and a construction kit, used for building structures. \layout Standard During a game of Tremulous, each team occupies one of three stages of developmen t. These stages are reached by accruing more than a specific total number of kills by the whole team. Each new stage unlocks new classes, upgrades and buildable structures. If one team reaches a stage significantly earlier than the other team it stands a better chance of defeating the opposing team. \layout Standard Section \begin_inset LatexCommand \ref{sec:Game} \end_inset details the content of the game including the various controls that are used to play. Section \begin_inset LatexCommand \ref{sec:Technical} \end_inset describes some technical aspects of how Tremulous works. It is not necessary to read this section in order to play the game. \layout Section \begin_inset LatexCommand \label{sec:Game} \end_inset Game \layout Subsection Aliens \layout Standard Two classes are available upon joining the alien team: the Dretch and the Granger. As you gain kills, you may use your earned frags to evolve into higher classes with the \noun on Use Structure/Evolve \noun default button. The alien team is mostly limited to melee attacks and must use stealth and speed to defeat the longer range humans. All aliens automatically regenerate health at a slow rate. \layout Subsubsection Classes \layout Standard \align center \begin_inset Tabular \begin_inset Text \layout Standard \emph on Granger \end_inset \begin_inset Text \layout Standard \end_inset \begin_inset Text \layout Standard \begin_inset Graphics filename granger.jpg scale 85 \end_inset \end_inset \begin_inset Text \layout Standard \end_inset \begin_inset Text \layout Standard Cost: 0 \end_inset \begin_inset Text \layout Standard Stage: 1 \end_inset \end_inset \layout Standard \align center \begin_inset Tabular \begin_inset Text \layout Standard Ability \end_inset \begin_inset Text \layout Standard Control \end_inset \begin_inset Text \layout Standard \end_inset \begin_inset Text \layout Standard Build \end_inset \begin_inset Text \layout Standard \noun on Primary Attack \end_inset \begin_inset Text \layout Standard \end_inset \begin_inset Text \layout Standard Destroy Structure \end_inset \begin_inset Text \layout Standard \noun on Deconstruct Structure \noun default on an alien structure \end_inset \begin_inset Text \layout Standard \end_inset \end_inset \layout Standard The \emph on Granger \emph default is the alien team's builder class. \noun on Primary Attack \noun default will bring up a menu of structures available for building.

Each .particle file can contain an arbitrary number of discrete particle systems, much like a .shader file can house many shaders. A particle system is declared by a name followed by curly braces within which the functionality of the particle system is defined. For example: \layout LyX-Code aShinyNewParticleSystem { } \layout Standard Inside the particle system declaration are placed up to four particle ejectors. Ejectors are identified by the keyword ejector and curly braces: \layout LyX-Code aShinyNewParticleSystem \layout LyX-Code { \layout LyX-Code ejector { } \layout LyX-Code ejector { } \layout LyX-Code } \layout Standard The role of the particle ejector is to create some number of new particles at a defined rate. These attributes are controlled by the following parameters: \layout Itemize \emph on count |infinite \emph default - the number of particles this ejector will spawn. \layout Itemize \emph on delay \emph default - the delay in msec before the ejector starts spawning. \layout Itemize \emph on period \emph default - the period between particle ejections. \layout Standard It is perfectly acceptable to have an initial period of zero. In this case the number of particles specified by the count keyword will be ejected at once. It is not permissible to have count infinite and a period of zero for obvious reasons. \layout Standard At ejection time each ejector creates up to four new particles based on templates. These are specified in the ejector section using the particle keyword: \layout LyX-Code aShinyNewParticleSystem \layout LyX-Code { \layout LyX-Code ejector \layout LyX-Code { \layout LyX-Code particle { } \layout LyX-Code particle { } \layout LyX-Code count 50 \layout LyX-Code delay 0 \layout LyX-Code period 0 - 0 \layout LyX-Code } \layout LyX-Code } \layout Standard Each particle template has a number of attributes: \layout Itemize \emph on shader |sync ... \emph default - this specifies the shaders to use for the particle. The frame rate can be set to a static rate or the \emph on sync \emph default parameter can be used in which case the frame rate will be synchronised to the lifetime of the particle such that the first frame is displayed on birth and the last frame is displayed immediately before death. \layout Itemize \emph on displacement \emph default - a static displacement about the attachment point. The \emph on variance \emph default parameter specifies a random displacement in all axes. \layout Itemize \emph on normalDisplacement \emph default - for particle systems that have their normal set (impact particle systems for example) this specifies the magnitude of a displacement along the normal. \layout Itemize \emph on velocityType static|tag|cent|normal \emph default - this specifies how the particle will compute its initial velocity. \emph on static \emph default means it is specified statically in the .particle file, \emph on tag \emph default means the velocity is in the direction of the tag it is attached to, \emph on cent \emph default means the velocity is in the direction of the cent it is attached to and \emph on normal \emph default means the velocity is in the direction of the particle system normal. \layout Itemize \emph on velocityDir linear|point \emph default - this specifies whether the initial velocity is computed as a simple direction or as the direction towards a secondary point (defined by \emph on velocityPoint \emph default or dynamically through \emph on velocityType cent \emph default ). \layout Itemize \emph on velocity \emph default - for when \emph on velocityType \emph default \emph on static \emph default is present this specifies the direction. The \emph on variance \emph default here is specified in degrees e.g. "~5" - up to 5 degrees deviation. \layout Itemize \emph on velocityMagnitude \emph default - the magnitude of the velocity. \layout Itemize \emph on velocityPoint \emph default - for when \emph on velocityType static \emph default and \emph on velocityDir point \emph default are present this specifies the point to move towards. \layout Itemize \emph on parentVelocityFraction \emph default - for when the particle system is attached to a cent this specifies the fraction of the cent's velocity that is added to the particle's velocity. \layout Itemize \emph on accelerationType static|tag|cent|normal \emph default - this specifies how the particle will compute its acceleration. \emph on static \emph default means it is specified statically in the .particle file, \emph on tag \emph default means the acceleration is in the direction of the tag it is attached to, \emph on cent \emph default means the acceleration is in the direction of the cent it is attached to and \emph on normal \emph default means the acceleration is in the direction of the particle system normal. \layout Itemize \emph on accelerationDir linear|point \emph default - this specifies whether the acceleration is computed as a simple direction or as the direction towards a secondary point (defined by \emph on accelerationPoint \emph default or dynamically through \emph on accelerationType cent \emph default ). \layout Itemize \emph on acceleration \emph default - for when \emph on accelerationType \emph default static is present this specifies the direction.

If this is set to 0.0 the particle won't collide. When \emph on cull \emph default is used particles are culled as soon as they collide with objects. \layout Itemize \emph on overdrawProtection \emph default - cull particles that occupy a large amount of screen space. \layout Itemize \emph on realLight \emph default - light particles using the lightgrid instead of fullbright. \layout Itemize \emph on cullOnStartSolid \emph default - cull particles that are spawned inside brushes. \layout Itemize \emph on radius \emph default - the radius of the particle throughout its lifetime. The \emph on delay \emph default parameter specifies the time in msec before radius scaling begins. The \emph on initial \emph default and \emph on final \emph default parameters specify the radii of the particle in quake units. \layout Itemize \emph on alpha \emph default - the alpha of the particle throughout its lifetime. The \emph on delay \emph default parameter specifies the time in msec before alpha scaling begins. The \emph on initial \emph default and \emph on final \emph default parameters specify the alpha of the particle where 1.0 is totally opaque and 0.0 is totally transparent. \layout Itemize \emph on rotation \emph default - the rotation of the particle throughout its lifetime. The \emph on delay \emph default parameter specifies the time in msec before the rotation begins. The \emph on initial \emph default and \emph on final \emph default parameters specify the rotation of the particle in degrees. \layout Itemize \emph on lifeTime
