It can still interact with other things, // but only as the instigator (missiles will run into other // things, but nothing can run into a missile). // Each block in the grid is 128*128 units, and knows about // every line_t that it contains a piece of, and every // interactable actor that has its origin contained. // // A valid actor is an actor that has the proper subsector_t // filled in for its xy coordinates and is linked into the // sector from which the subsector was made, or has the // MF_NOSECTOR flag set (the subsector_t needs to be valid // even if MF_NOSECTOR is set), and is linked into a blockmap // block or has the MF_NOBLOCKMAP flag set. // Links should only be modified by the P_[Un]SetThingPosition() // functions. // Do not change the MF_NO* flags while a thing is valid. // // Any questions? // enum { // --- mobj.flags --- MF_SPECIAL = 0x00000001, // call P_SpecialThing when touched MF_SOLID = 0x00000002, MF_SHOOTABLE = 0x00000004, MF_NOSECTOR = 0x00000008, // don't use the sector links // (invisible but touchable) MF_NOBLOCKMAP = 0x00000010, // don't use the blocklinks // (inert but displayable) MF_AMBUSH = 0x00000020, // not activated by sound; deaf monster MF_JUSTHIT = 0x00000040, // try to attack right back MF_JUSTATTACKED = 0x00000080, // take at least one step before attacking MF_SPAWNCEILING = 0x00000100, // hang from ceiling instead of floor MF_NOGRAVITY = 0x00000200, // don't apply gravity every tic // movement flags MF_DROPOFF = 0x00000400, // allow jumps from high places MF_PICKUP = 0x00000800, // for players to pick up items MF_NOCLIP = 0x00001000, // player cheat MF_INCHASE = 0x00002000, // [RH] used by A_Chase and A_Look to avoid recursion MF_FLOAT = 0x00004000, // allow moves to any height, no gravity MF_TELEPORT = 0x00008000, // don't cross lines or look at heights MF_MISSILE = 0x00010000, // don't hit same species, explode on block MF_DROPPED = 0x00020000, // dropped by a demon, not level spawned MF_SHADOW = 0x00040000, // actor is hard for monsters to see MF_NOBLOOD = 0x00080000, // don't bleed when shot (use puff) MF_CORPSE = 0x00100000, // don't stop moving halfway off a step MF_INFLOAT = 0x00200000, // floating to a height for a move, don't // auto float to target's height MF_INBOUNCE = 0x00200000, // used by Heretic bouncing missiles MF_COUNTKILL = 0x00400000, // count towards intermission kill total MF_COUNTITEM = 0x00800000, // count towards intermission item total MF_SKULLFLY = 0x01000000, // skull in flight MF_NOTDMATCH = 0x02000000, // don't spawn in death match (key cards) MF_SPAWNSOUNDSOURCE = 0x04000000, // Plays missile's see sound at spawning object.
