WARNING: MODIFYING GUILD WARS 2 THROUGH ANY 3RD PARTY TOOLS IS NOT SUPPORTED BY ARENANET OR NCSOFT.
DO NOT CONTACT SUPPORT ABOUT GAME CLIENT ISSUES WHILE USING THIS TOOL. THERE IS NO HELP OR WARRANTY.
THIS IS ENTIRELY AT YOUR OWN RISK AND YOU ASSUME ALL RESPONSIBILITY.
how to install, update, or uninstall
place d3d11.dll next to gw2-64.exe while the game is not running, optionally can be renamed to dxgi.dll.
addons and arcdps config folder will be created next to gw2-64.exe after starting the client.
to update, replace dll.
to reset, exit gw2 and remove the config folder above.
to remove, exit gw2 and delete the dll.
expect to have to update after major game changes.
most errors will disable logging and extension data.
how to use
don't be a dick.
by default, holding alt and shift is required for hotkeys, t is the hotkey for options.
right click on windows to bring up their independent context menu options (if available).
something isn't working
check your 'gw2 install dir/addons/arcdps/' folder for an arcdps.log.
if nothing is drawn make sure the dll is in the right place.
if the game crashes at character select, some other application is interfering (razer cortex, razer synapse).
if you get an image modified error, some other application is interfering (eg bitdefender, citrix 22, razer cortex, razer synapse, groupy, overwolf).
if windows are drawn but a hotkey isn't working, some other application may have a global hook installed (zoom).
if you get a file creation error, make sure gw2 has read/write permission to the paths mentioned.
if you notice an issue in accuracy, compare area skills vs self skills, try and isolate which gear/buff/trait may be causing it.
if you suspect arcdps as the cause of a crash, remove all addons and chainloads and try to repeat the crash.
if your issue is not in the discord pins, describe it in detail and attach the latest complete arcdps log.
evtc logging
pve/wvw: starts on first player combat enter, boss set by damage event on boss, stops when all players exit combat.
map: starts on joining an instance type map, stops on leaving map.
npc id for pve logs can be found via detail window and noting species in title, or tooltip in target list after attacking.
logs are written to 'documents/gw2/addons/arcdps/arcdps.cbtlogs/.../date-time.evtc' by default.
extensions and parsing data
most extensions and links to parsing tools can be found on elite insights' discord.
place next to gw2 exe or in gw2 install dir/bin64/.
