// FRICTION EFFECTS
|
|
//
|
|
// phares 3/12/98: Start of friction effects
|
|
|
|
// As the player moves, friction is applied by decreasing the x and y
|
|
// velocity values on each tic. By varying the percentage of decrease,
|
|
// we can simulate muddy or icy conditions. In mud, the player slows
|
|
// down faster. In ice, the player slows down more slowly.
|
|
//
|
|
// The amount of friction change is controlled by the length of a linedef
|
|
// with type 223. A length < 100 gives you mud. A length > 100 gives you ice.
|
|
//
|
|
// Also, each sector where these effects are to take place is given a
|
|
// new special type _______. Changing the type value at runtime allows
|
|
// these effects to be turned on or off.
|
|
//
|
|
// Sector boundaries present problems. The player should experience these
|
|
// friction changes only when his feet are touching the sector floor. At
|
|
// sector boundaries where floor height changes, the player can find
|
|
// himself still 'in' one sector, but with his feet at the floor level
|
|
// of the next sector (steps up or down). To handle this, Thinkers are used
|
|
// in icy/muddy sectors. These thinkers examine each object that is touching
|
|
// their sectors, looking for players whose feet are at the same level as
|
|
// their floors. Players satisfying this condition are given new friction
|
|
// values that are applied by the player movement code later.
|
|
|
|
//
|
|
// killough 8/28/98:
|
|
//
|
|
// Completely redid code, which did not need thinkers, and which put a heavy
|
|
// drag on CPU. Friction is now a property of sectors, NOT objects inside
|
|
// them. All objects, not just players, are affected by it, if they touch
|
|
// the sector's floor. Code simpler and faster, only calling on friction
|
|
// calculations when an object needs friction considered, instead of doing
|
|
// friction calculations on every sector during every tic.
|
|
//
|
|
// Although this -might- ruin Boom demo sync involving friction, it's the only
|
|
// way, short of code explosion, to fix the original design bug. Fixing the
|
|
// design bug in Boom's original friction code, while maintaining demo sync
|
|
// under every conceivable circumstance, would double or triple code size, and
|
|
// would require maintenance of buggy legacy code which is only useful for old
|
|
// demos. Doom demos, which are more important IMO, are not affected by this
|
|
// change.
|
|
//
|
|
// [RH] On the other hand, since I've given up on trying to maintain demo

// sync between versions, these considerations aren't a big deal to me.
