During a keynote presentation at the {{w|Games for Change|Games For Change}} festival in 2011, Valve director Gabe Newell mentioned that the company was beginning to work with schools to build curricula around ''Portal 2'', looking into "how to teach attraction, repulsion... [they] need to be clear on what their metrics are... what the outcome is, what they're optimizing for".<ref>[http://kotaku.com/5814405/ Kotaku: "Liveblogging Whatever Smart Stuff Gabe Newell Has to Say Today"].</ref> | During a keynote presentation at the {{w|Games for Change|Games For Change}} festival in 2011, Valve director Gabe Newell mentioned that the company was beginning to work with schools to build curricula around ''Portal 2'', looking into "how to teach attraction, repulsion...

=== Portal 2 === | |||
==== Save/Load Abuse ==== | |||
'''Save/Load Abuse''' (SLA)<ref>https://rules.portal2.sr/#saveload-abuse-sla</ref> is defined as using any unnatural load or level transition (i.e. anything other than touching a changelevel trigger in the map) in order to affect the chance of some event occurring or make an event possible. For instance, saveload clipping is considered SLA, since it achieves an effect which would otherwise be impossible. Similarly, loading saves to retry lucky door skip in sp_a2_bridge_the_gap is SLA, as it affects the overall chance of successfully getting through the door. Exceptions are made to this rule for physics RNG specifically, so that loading saves and getting different physics RNG is not considered SLA, since this RNG is prevalant to the point of being unavoidable. | |||
==== Out of Bounds ==== | |||
We define the player themselves as being out of bounds<ref>https://rules.portal2.sr/#out-of-bounds-oob</ref> if a) the player's eye position goes out of bounds or b) all 8 vertices of the player's bounding box go out of bounds... | |||
The Source Engine has a strict technical definition of whether a point is "out of bounds" based on its BSP world system (a point is out of bounds if it is in a CONTENTS_SOLID leaf and not within a brush)... | |||
==== Pause Abuse ==== | |||
'''Pause Abuse'''<ref>https://rules.portal2.sr/#pause-abuse</ref> is defined as using game pauses (via the ESC key, gameui commands, or opening the developer console) to affect the chance of some event occurring, make an event possible, or otherwise contribute to the run. For instance, the Betsrighter jump in sp_a1_wakeup can be done far more consistently by console pausing as you land - as such, pausing at this moment in the run is considered pause abuse, as it affects your chances of getting the jump. More subtly, pausing while lining up a precise shot is also pause abuse, since the time you are paused can allow you time to read your coordinates and prepare to move your mouse correctly. | |||
