example.cpp has the code i use to write out evtc files. check file header for environment: evtc bytes for filetype, arcdps build yyyymmdd for compatibility, target species id for boss/manual. create agents and skills table from evtc, consider dynamic expansion - some nameless/combatless agents may not be written. skill and agent names use utf8 encoding. evtc_agent.name is a combo string on players - character name account name subgroup str literal . add u16 field to the agent table, agents[x].instance_id, initialized to 0. add u64 fields agents[x].first_aware initialized to 0, and agents[x].last_aware initialized to u64max. add u64 field agents[x].master_addr, initialized to 0. if evtc_agent.is_elite == 0xffffffff && upper half of evtc_agent.prof == 0xffff, agent is a gadget with pseudo id as lower half of evtc_agent.prof (volatile id). if evtc_agent.is_elite == 0xffffffff && upper half of evtc_agent.prof != 0xffff, agent is a character with species id as lower half of evtc_agent.prof (reliable id). if evtc_agent.is_elite != 0xffffffff, agent is a player with profession as evtc_agent.prof and elite spec as evtc_agent.is_elite. gadgets do not have true ids and are generated through a combination of gadget parameters - they may collide with characters and should be treated separately. iterate through all events, assigning instance ids and first/last aware ticks. set agents[x].instance_id = cbtevent.src_instid where agents[x].addr == cbtevent.src_agent && !cbtevent.is_statechange. set agents[x].first_aware = cbtevent.time on first event, then all consecutive event times to agents[x].last_aware. iterate through all events again, this time assigning master agent. set agents[z].master_agent on encountering cbtevent.src_master_instid != 0. agents[z].master_addr = agents[x].addr where agents[x].instance_id == cbtevent.src_master_instid && agent[x].first_aware < cbtevent.time < last_aware. iterate through all events one last time, this time parsing for the data you want. cbtevent.src_agent and cbtevent.dst_agent should be used to associate event data with local data. parse event type order should check cbtevent.is_statechange > cbtevent.is_activation > cbtevent.is_buffremove. cbtevent.is_statechange will do the heavy lifting of non-internal and parser-requested events - make sure to ignore unknown statechange types. if you would like to see an event not obtainable through my cbtevent struct, let me know. on cbtevent.is_activation == cancel_fire or cancel_cancel, value will be the ms duration of the time spent in animation. on cbtevent.is_activation == normal or quickness, value will be the ms duration of the expected animation time. on cbtevent.is_buffremove, value will be the total duration removed of the stack/s, buff_dmg will be the duration of the longest stack. if they are all 0, it will be a buff application (!cbtevent.is_buffremove && cbtevent.is_buff) or physical hit (!cbtevent.is_buff). on physical, cbtevent.value will be the damage done (negative = healing, if ever added). on physical, cbtevent.result will be the result of the attack. on buff && !cbtevent.buff_dmg && cbtevent.value, cbtevent.value will be the millisecond duration applied. cbtevent.overstack will be apx overstack in ms. on buff && !cbtevent.buff_dmg && !cbtevent.value, it is negated condition damage via invuln or resistance. on buff && cbtevent.buff_dmg && !cbtevent.value, cbtevent.buff_dmg will be the approximate damage done on tick (negative = healing, if ever added). raid boss ids: vale guardian = 0x3C4E gorseval = 0x3C45 sabetha = 0x3C0F slothasor = 0x3EFB trio = 0x3ED8, 0x3F09, 0x3EFD matthias = 0x3EF3 stk = keep construct = 0x3F6B xera = 0x3F76, 0x3F9E cairn = 0x432A overseer = 0x4314 samarog = 0x4324 deimos = 0x4302 some fractal ids (thanks /u/hollywood_rag): https://pastebin.com/3GpfDfGe base npc stats (for levels 0 to 84): def = { 123, 128, 134, 138, 143, 148, 153, 158, 162, 167, 175, 183, 185, 187, 190, 192, 202, 206, 210, 214, 220, 224, 239, 245, 250, 256, 261, 267, 285, 291, 311, 320, 328, 337, 356, 365, 385, 394, 402, 411, 432, 443, 465, 476, 486, 497, 517, 527, 550, 561, 575, 588, 610, 624, 649, 662, 676, 690, 711, 725, 752, 769, 784, 799, 822, 837, 878, 893, 909, 924, 949, 968, 1011, 1030, 1049, 1067, 1090, 1109, 1155, 1174, 1223, 1247, 1271, 1295, 1319} pwr = { 162, 179, 197, 214, 231, 249, 267, 286, 303, 322, 344, 367, 389, 394, 402, 412, 439, 454, 469, 483, 500, 517, 556, 575, 593, 612, 622, 632, 672, 684, 728, 744, 761, 778, 820, 839, 885, 905, 924, 943, 991, 1016, 1067, 1093, 1119, 1145, 1193, 1220, 1275, 1304, 1337, 1372, 1427, 1461, 1525, 1562, 1599, 1637, 1692, 1731, 1802, 1848, 1891, 1936, 1999, 2045, 2153, 2201, 2249, 2298, 2368, 2424, 2545, 2604, 2662, 2723, 2792, 2854, 2985, 3047, 3191, 3269, 3348, 3427, 3508} attr = { 5, 10, 17, 22, 27, 35, 45, 50, 55, 60, 68, 76, 84, 92, 94, 95, 103, 108, 112, 116, 123, 129, 140, 147, 153, 160, 166, 171, 186, 192, 208, 219, 230, 238, 253, 259, 274, 279, 284, 290, 304, 317, 339, 353, 366, 380, 401, 416, 440, 454, 471, 488, 514, 532, 561, 579, 598, 617, 643, 662, 696, 718, 741, 765, 795, 818, 866, 891, 916, 941, 976, 1004, 1059, 1089, 1119, 1149, 1183, 1214, 1274, 1307, 1374, 1413, 1453, 1493, 1534} enums and structs: /* iff */ enum iff { IFF_FRIEND, // green vs green, red vs red IFF_FOE, // green vs red IFF_UNKNOWN // something very wrong happened }; /* combat result (physical) */ enum cbtresult { CBTR_NORMAL, // good physical hit CBTR_CRIT, // physical hit was crit CBTR_GLANCE, // physical hit was glance CBTR_BLOCK, // physical hit was blocked eg. mesmer shield 4 CBTR_EVADE, // physical hit was evaded, eg. dodge or mesmer sword 2 CBTR_INTERRUPT, // physical hit interrupted something CBTR_ABSORB, // physical hit was "invlun" or absorbed eg. guardian elite CBTR_BLIND, // physical hit missed CBTR_KILLINGBLOW // physical hit was killing hit }; /* combat activation */ enum cbtactivation { ACTV_NONE, // not used -
