When using attachTo with "proxy:\a3\characters_f\proxies\weapon.001" as memPoint and followBoneRotation set to true and an offset, the attached objects shifts up and down relative to the weapon when aiming up and down. Since there is no weapon animation running, the object should look just like a weapon attachment, but it doesn't.
private _model = getText (configFile >> "CfgWeapons" >> primaryWeapon player >> "model"); private _dummy = createSimpleObject [_model, [0, 0, 0], true]; private _proxyOffset = _dummy selectionPosition ["\a3\data_f\proxies\weapon_slots\SIDE.001", 1]; _proxyOffset = [_proxyOffset#1, _proxyOffset#0 * -1, _proxyOffset#2]; deleteVehicle _dummy; private _sphere = createSimpleObject ["Sign_Sphere10cm_F", [0, 0, 0]]; _sphere attachTo [player, _proxyOffset, "proxy:\a3\characters_f\proxies\weapon.001", true]; _sphere setObjectScale 0.1;
It's because "followBone" attaches the object to the "memory" LOD, which doesn't match the visual LOD:
_w = currentWeapon player;
_cfg = configFile >> "CfgWeapons" >> _w;
_m = getText(_cfg >> "model");
_o = createSimpleObject [_m, [0,0,0]];
_o attachTo [player, [0,0,0], "proxy:\a3\characters_f\proxies\weapon.001", true];
_o setDir 90
onEachFrame {
_w = primaryWeapon player;
//update weapon info upon weapon switch
if (_w != player getVariable ["last_weapon", "?"]) then {
_cfg = configFile >> "CfgWeapons" >> _w;
_m = getText(_cfg >> "model");
//if (_m select [0,1] == "\") then {_m = _m select [1]};
_o = createSimpleObject [_m, [0,0,0], true];
_off = _o selectionPosition [getText(_cfg >> "muzzlePos"), "memory"];
_off = _off apply {[_x]};
deleteVehicle _o;
player setVariable ["offset", _off];
player setVariable ["last_weapon", _w];
player setVariable ["proxy",
[
"proxy:\a3\characters_f\proxies\pistol.001",
"proxy:\a3\characters_f\proxies\weapon.001",
"proxy:\a3\characters_f\proxies\launcher.001",
"proxy:\a3\characters_f\proxies\binoculars.001"
] select (([1, 4, 4096] find getNumber(_cfg >> "type")) + 1)
];
};
_offset = player getVariable ["offset", []];
_proxy = player getVariable ["proxy", ""];
player selectionVectorDirAndUp [_proxy, 1e15] params ["_vy", "_vz"];
_pos = player selectionPosition [_proxy, 1e15] vectorAdd[0.33,0,0];
_vx = _vy vectorCrossProduct _vz;
_mat = matrixTranspose [_vx, _vy, _vz];
_pos = _pos vectorAdd flatten(_mat matrixMultiply _offset);
_p1 = player modelToWorldVisualWorld _pos;
_p2 = _p1 vectorAdd (player vectorModelToWorldVisual (_vy vectorMultiply 1000));
drawLine3D [ASLtoAGL _p1, ASLtoAGL _p2, [1,0,0,1]];
}I don't quite understand why the memory LOD is so far off the visual LOD, but maybe as a workaround you could offer another parameter to set what LOD to use.
It would make more sense to use a visual LOD by default in my opinion, attachTo is a visual thing, but I can understand that you probably don't want to break existing code.
