// PUSH/PULL EFFECT
|
||||||
|
//
|
||||||
|
// phares 3/20/98: Start of push/pull effects
|
||||||
|
//
|
||||||
|
// This is where push/pull effects are applied to objects in the sectors.
|
||||||
|
//
|
||||||
|
// There are four kinds of push effects
|
||||||
|
//
|
||||||
|
// 1) Pushing Away
|
||||||
|
//
|
||||||
|
// Pushes you away from a point source defined by the location of an
|
||||||
|
// MT_PUSH Thing. The force decreases linearly with distance from the
|
||||||
|
// source. This force crosses sector boundaries and is felt w/in a circle
|
||||||
|
// whose center is at the MT_PUSH. The force is felt only if the point
|
||||||
|
// MT_PUSH can see the target object.
|
||||||
|
//
|
||||||
|
// 2) Pulling toward
|
||||||
|
//
|
||||||
|
// Same as Pushing Away except you're pulled toward an MT_PULL point
|
||||||
|
// source. This force crosses sector boundaries and is felt w/in a circle
|
||||||
|
// whose center is at the MT_PULL. The force is felt only if the point
|
||||||
|
// MT_PULL can see the target object.
|
||||||
|
//
|
||||||
|
// 3) Wind
|
||||||
|
//
|
||||||
|
// Pushes you in a constant direction. Full force above ground, half
|
||||||
|
// force on the ground, nothing if you're below it (water).
|
||||||
|
//
|
||||||
|
// 4) Current
|
||||||
|
//
|
||||||
|
// Pushes you in a constant direction. No force above ground, full
|
||||||
|
// force if on the ground or below it (water).
|
||||||
|
//
|
||||||
|
// The magnitude of the force is controlled by the length of a controlling
|
||||||
|
// linedef. The force vector for types 3 & 4 is determined by the angle
|
||||||
|
// of the linedef, and is constant.
|
||||||
|
//
|
||||||
|
// For each sector where these effects occur, the sector special type has
|
||||||
|
// to have the PUSH_MASK bit set. If this bit is turned off by a switch
|
||||||
|
// at run-time, the effect will not occur. The controlling sector for
|
||||||
|
// types 1 & 2 is the sector containing the MT_PUSH/MT_PULL Thing.
