Description
- Description:
- Description needed
- Problems:
- For some unknown reason, the "PathCalculated" Event Handler is fired twice, first with calculated path and second with array consisting of 2 elements, which are identical and are equal to the end point. See Example 3 & 4 for a workaround.
- Groups:
- Object Manipulation
Syntax
- Syntax:
- Syntax needed
- Parameters:
- type: String - Vehicle type to simulate (see description)
- behaviour: String - AI behaviour, one of "CARELESS", "SAFE", "AWARE", "COMBAT" or "STEALTH"
- from: Array - Start position in format [x,y,z]
- to: Array - End position in format [x,y,z]
- Return Value:
- Return value needed
Examples
- Example 1:
calculatePath ["car", "safe", [2150.67,5778.19,0], [2184.11,5802.28,0]]- Example 2:
- Draws the path from South West to North East of Agia Marina:
(calculatePath ["man","safe",[2832.9,5927.79,0],[3107.46,6036.61,0]]) addEventHandler ["PathCalculated", { { private _marker = createMarker ["marker" + str _forEachIndex, _x]; _marker setMarkerType "mil_dot"; _marker setMarkerText str _forEachIndex; } forEach (_this select 1); }] - Example 3:
- Alternative usage of calculatePath functionality that is free of double execution bug (and calculatePath command):
private _agent = createAgent [typeOf player, position player, [], 0, "NONE"]; _agent addEventHandler ["PathCalculated", { { private _marker = createMarker ["marker" + str _forEachIndex, _x]; _marker setMarkerType "mil_dot"; _marker setMarkerText str _forEachIndex; } forEach (_this select 1); }]; _agent setDestination [player getRelPos [500, 0], "LEADER PLANNED", true]; - Example 4:
- Same as above but for a vehicle:
private _agent = createAgent [typeOf player, position player, [], 0, "NONE"]; private _car = "B_Quadbike_01_F" createVehicle position player; _agent moveInDriver _car; _agent addEventHandler ["PathCalculated", { { private _marker = createMarker ["marker" + str _forEachIndex, _x]; _marker setMarkerType "mil_dot"; _marker setMarkerText str _forEachIndex; } forEach (_this select 1); }]; _agent setDestination [player getRelPos [500, 0], "LEADER PLANNED", true];

- When using this command to get the predicted path of vehicles driving and having them stay on roads (not go cross country) is important, the best vehicle to use is "wheeled_APC" and careless behaviour.
