    Game structure of agents

    Evening,

    in GW1 there was a static pointer to an agentStruct conatinig certain agents (including yourself or the target). There were offsets to agentIDs (character and target) so that you could read e.g. both yourselve's and target's hp from memory. Like:

    AgentStructBase + 0x4C(own agentID) + 0x90(e.g. health)
    AgentStructBase + 0x54(targetID) + 0x48(e.g. target health)

    How is the stucturing of agents in GW2?

    Greetings

    It's different in Gw2, you need to read in this order :

    Player : CharacterClientContext->controlledCharacter->CharClientHealth->currentHealth
    Target : AgentSelectionContext->selectedAgent->charClient->CharClientHealth->currentHealth

    Hi,

    thanks for the info. So I found 2 float values for current health (0x0F536A7C, 0x0FA74A8. From there I wanted to find the pointer to CharClientHealth by searching for 4 byte values step by step HealthAdress - 4 (0x0FA74A84, 0x0FA74A80, 0x0FA74A7C, 0x0FA74A7 - no results. If the CharClientHealth structure isnt too big, shouldn't I have received an adress?
    Here's a picture of what I mean:

    You need first to find the pointer of the ChCliContext class, in this one there is a pointer to the ChCliCharacter (named controlledCharacter), then is the ChCliCharacter class, there is a pointer to the ChCliHealth class, which contains the current and max value as float

    Btw, your pic of the structure is wrong wrong that way

    So I found a static pointer at 0x1656FD4 and created a working routine to read the currentHealth. When I changed the area, the routine failed. Further analysis revealed, that the offset 0x5670 added to the value of 0x1656FD4 changed. The problem is the following:
    I find to adresses for currentHealth: 0x0FC19BDC and 0x1096EB38.
    I look what accesses 0x0FC19... and search for the suggested value. I find one to three results, but the values of the adresses change like mad. Access/write analysis revealed, that they change each other, so I do not receive any new information. So I discarded the 0x0FC19BDC result for current health.
    Then I tried write analysis of 0x1096EB38 (2nd result for currentHealth). I do not get any results for the suggested value. The other results seem to work circular, too.

    Now I am totally confused I do not know how I managed to find this one static pointer in the first place o.O. Is 0x1656FD4 even a good result or did I land elsewhere?

    Any help would be very much appreciated

    Edit:

    I experimented a bit and the problem for my best solution is that the value of pointer to the base of ControlledCharacterHealth mutates all the time. So when I read and add 0x18 (what seems to be the offset CharacterHealth -> CharacterHealthCurrentHealth), the value matches. But only sometimes.
