[C#|.NET] GET_SAFE_COORD_FOR_PED, how?

[GeorgeZhang]

GET_SAFE_COORD_FOR_PED(float x, float y, float z, BOOL onGround, Vector3 *outPosition, int flags)

How to use this Native and what it does exactly? ScriptHookVDotNet doesn't allow me to fill in a Vector3 in the parameters, so is there a way to use this in C#?

C# is a sh*it, use c++ instead

But I don't use C# for GTA scripting. C++ is way easier and better.

Thanks for replying but you wouldn't convert a whole project from C# to C++ just to make one native work, right? This still needs to be solved.

try this

        Vector3 GET_SAFE_COORD_FOR_PED(Vector3 pos, bool onGround, int flags)        {            OutputArgument Out = new OutputArgument();            if (Function.Call<bool>(Hash.GET_SAFE_COORD_FOR_PED, pos.X, pos.Y, pos.Z, onGround, Out, flags))            {                return Out.GetResult<Vector3>();            }            else            {                return Vector3.Zero;            }        }

thanks, I'll try this later.

the native looks for a safe/available position for a ped around the parameter coordinates X Y Z. It returns true if it was able to find a position, and it assigns the coordinates for said position to the "Vector3 *outPosition" pointer-parameter. So you declare a new Vector3 variable for the safe spot and call the function with a pointer to that variable as the "outPosition" parameter, and - if it returns true - the Vector3 you passed it will be filled with the safe-spot coordinates

Thanks for the descriptions.The problem is, you can't pass a Vector3 in the parameters. I haven't tested it but Lestium's method seems promising, so I will try.

You dont pass it a Vector3; you pass it a pointer to a Vector3 (so have an "&" symbol in front of the parameter). This is why it is able to change the value of "outPosition" when it only returns a boolean (rather than returning a Vector3, as one might expect). Here's a C++ example I've used where a ped (called "ped") parachutes to a safe spot near his target (called "target")

Vector3 targetPosition = ENTITY::GET_ENTITY_COORDS(target);Vector3 safeSpot;if (PATHFIND::GET_SAFE_COORD_FOR_PED(targetPosition.x, targetPosition.y, targetPosition.z, true, &safeSpot, 0))     AI::TASK_PARACHUTE_TO_TARGET(ped, safeSpot.x, safeSpot.y, safeSpot.z);

the way it works is kind of similar to how the PED::GET_PED_NEARBY_PEDS() native works -- which returns an integer that is the only the total number of nearby peds, but it actually records the IDs of the nearby peds within a pointer array that you have to pass it as one of its parameters

I know what you mean with pointers, but .net just won't accept it, it displays errors no matter I pass Vector3/&Vector3, saying it's invalid arguments. I know it works in C++, and I know it returns whether a coords is found or not.

try this

        Vector3 GET_SAFE_COORD_FOR_PED(Vector3 pos, bool onGround, int flags)        {            OutputArgument Out = new OutputArgument();            if (Function.Call<bool>(Hash.GET_SAFE_COORD_FOR_PED, pos.X, pos.Y, pos.Z, onGround, Out, flags))            {                return Out.GetResult<Vector3>();            }            else            {                return Vector3.Zero;            }        }

Thanks, I guess it worked!
