Strange behavior of Task.GoTo

[Cyron43 130]

Hi,

I don't know what causes this behavior. Is it the .net scripthook (build from 05/21 installed) or is it the native function under the hood?

Anyway, when I try to let my player character walk towards a waypoint he just stands idle BUT when I set a waypoint anywhere in water he starts running and even follows pathways! At the time he gets into the water he even swims towards the waypoint. I just make this simple call:

 

Game.Player.Character.Task.GoTo(CommonFunctions.GetWaypoint().Position, ignorePaths: false);

Note: CommonFunctions is a static class from my own framework and contains (among other things) temporary implementations which didn't make it into the .net script hook yet. GetWaypoint() is one of those.

 

      public static Blip GetWaypoint()      {         try         {            return World.GetActiveBlips().FirstOrDefault(b => b.Type == 4);         }         catch(ArgumentNullException)         {            return null;         }      }

Edit to add: He must either be in the water or near the water at the beach. It only works if the waypoint is set somewhere in the ocean. It does not work on lakes. Edited June 5, 2015 by Cyron43

I've had this strange behavior too, I can't remember how exactly I did it, I'll post my Code as soon as I am back @home

Thanks. It seems this method (or native function) rather be named SwimTo.

[c39687 62]

i suspect it has something to do with the Z value of the position he is going to. Try something like this... and im not sure im using proper code so just make the necessary corrections (these methods existed in the old shdn)...

 

Vector3 goToPos = new Vector3(wayPoint.Position.X, wayPoint.Position.Y, wayPoint.Position.ToGround().Z);

 

ToGround is a wrapper for a native that gets the ground Z position, just search for it in the natives.h

[Graphicscore 35]

This is the code I used :

player.Task.GoTo(new GTA.Math.Vector3(2369.901F, 6614.253F, 234F), true);I think you have to do the ignore path to true , like in my case there was no street or something.

Now that brings up the question "what is the ground" when it comes to the ocean? One should think it's the bottom of the sea but technically it could be as well the height of the water surface (is that 0 anyway?). Ima do some more experiments and also with Driving style and the ignore path parameter (@Graphicscore).

Thanks for your replies, guys.

i would suspect the logical origin for Z is at sea level but it really could be an arbitry plane the developers picked. Just test it by printing ground z of a position where X,Y is over the ocean

 

here is the native btw... (not sure about the return type but BOOL is just an integer, it is different than bool and 0 represents false, use with Function.Call<int> i also suspect this declaration is not 100% accurate)

static  BOOL GET_GROUND_Z_FOR_3D_COORD(float x, float y, float z, float* groundZ) { return invoke<BOOL>(0xC906A7DAB05C8D2B, x, y, z, groundZ); } // 0xC906A7DAB05C8D2B 0xA1BFD5E0

[Cyron43 130]

Thanks c39687. I use World.GetGroundZ of the .net scripthook. Isn't that the same under the hood?

Anyway I did some tests with all combinations of parameters and here is what I got:

 

This editor sucks for real! I can't edit a table because all the formatting gets lost. Here is a png instead.

Note: walks/swims straight means he gets stuck at whatever obstacle is in the line between him and the waypoint.

[c39687 62]

before you task the ped to go somewhere try using...

 

 

static BOOL LOAD_ALL_PATH_NODES(BOOL p0) { return invoke<BOOL>(0x80E4A6EDDB0BE8D9, p0); } // 0x80E4A6EDDB0BE8D9 0xC66E28C3

 

 

use 1 to load all paths and 0 just loads paths around the player, not sure paths are the exact problem but them idling when you tell them to use a path may suggest the paths are not loaded

[c39687 62]

btw... when you change ignore paths you are using different natives to make the ped move, you may need to call other native functions as well to get this all to work... you can check the game scripts for examples of the context these natives are used in...

 

IgnorePaths = TASK_GO_STRAIGHT_TO_COORD

!IgnorePaths = TASK_FOLLOW_NAV_MESH_TO_COORD (you may need to call some native that loads the navmesh)

 

i really dont know how this all works in GTA but trial and error plus researching the game scripts may solve the problem

 

try researching how the natives relevant to "NavMeshes" are used...

o_0 just wow!

Thanks so much for your help, @c39687. That's gonna take some time to fiddle with.

BTW I used LoadAllPathNodes already but that didn't do it.

If I remember right , you can give the ped a custom Nav grid mesh (basically an array of Vector3s) where the entity would actually walk from Vector to Vector. If of course the route should be calculated automatically he can only use the Vector's given by the game, maybe you could try to ignore paths and walk to the nearest Vector of the Games Nav Mesh Grid and calculate your war from there on. Just a guess.

HEUREKA!
I got grey hairs over this the last days and you know what? It wasn't my fault! I thought, well just maybe there's something wrong with the GetGroundZ method in the .net scripthook. So I tried to recreate it myself and as I was reading the description in the natives DB some special words caught my attention:
"Note that if the specified position is below ground level, the function will output zero!"
AHA! The Z-value of a waypoint is always 0 and even the lowest terrain at Trevor's home is about 32 units in elevation. So GetGroundZ returns 0 as described!

With that in mind I went to the highest elevation on the map, the roof top of the cable car station on mount Chiliad and got a Z-value of about 797 units. Here is my simple solution:

      public static Vector3 ToGround(this Vector3 position)      {         position.Z = 1000.0f;         return new Vector3(position.X, position.Y, World.GetGroundZ(position));      }

With the help of this extension method the rest was a piece of cake.

      private void GoToWaypoint()      {         _isActive = !_isActive;         if(!_isActive)         {            Game.Player.Character.Task.ClearAll();            UI.Notify("Walking task should be released now.");            return;         }         var waypoint = CommonFunctions.GetWaypoint();         if(waypoint == null)         {            _isActive = false;            UI.Notify("No waypoint found.");            return;         }         UI.Notify("Character should be walking now.");         CommonFunctions.LoadAllPathNodes(true);         Game.Player.Character.Task.RunTo(waypoint.Position.ToGround(), ignorePaths: false);         Game.Player.Character.Task.ClearAll();      }

TADDAA! The route could not be calculated because the target was below ground but that issue is history now.

I wouldn't wonder if Autodrive is also less error prone now.

      private void GoToWaypoint()      {         _isActive = !_isActive;         if(!_isActive)         {            Game.Player.Character.Task.ClearAll();            UI.Notify("Walking task should be released now.");            return;         }         var waypoint = CommonFunctions.GetWaypoint();         if(waypoint == null)         {            _isActive = false;            UI.Notify("No waypoint found.");            return;         }         UI.Notify("Character should be walking now.");         CommonFunctions.LoadAllPathNodes(true);         Game.Player.Character.Task.RunTo(waypoint.Position.ToGround(), ignorePaths: false);         Game.Player.Character.Task.ClearAll();      }

TADDAA! The route could not be calculated because the target was below ground but that issue is history now.

I wouldn't wonder if Autodrive is also less error prone now.

 

Oh , nice. ! Maybe you should post that at the github page of the .NET scripthook though

HEUREKA!

I got grey hairs over this the last days and you know what? It wasn't my fault! I thought, well just maybe there's something wrong with the GetGroundZ method in the .net scripthook. So I tried to recreate it myself and as I was reading the description in the natives DB some special words caught my attention:

"Note that if the specified position is below ground level, the function will output zero!"

AHA! The Z-value of a waypoint is always 0 and even the lowest terrain at Trevor's home is about 32 units in elevation. So GetGroundZ returns 0 as described!

With that in mind I went to the highest elevation on the map, the roof top of the cable car station on mount Chiliad and got a Z-value of about 797 units. Here is my simple solution:

      public static Vector3 ToGround(this Vector3 position)      {         position.Z = 1000.0f;         return new Vector3(position.X, position.Y, World.GetGroundZ(position));      }

With the help of this extension method the rest was a piece of cake.

      private void GoToWaypoint()      {         _isActive = !_isActive;         if(!_isActive)         {            Game.Player.Character.Task.ClearAll();            UI.Notify("Walking task should be released now.");            return;         }         var waypoint = CommonFunctions.GetWaypoint();         if(waypoint == null)         {            _isActive = false;            UI.Notify("No waypoint found.");            return;         }         UI.Notify("Character should be walking now.");         CommonFunctions.LoadAllPathNodes(true);         Game.Player.Character.Task.RunTo(waypoint.Position.ToGround(), ignorePaths: false);         Game.Player.Character.Task.ClearAll();      }

I created an issue ticket with a link to this post, my friend.

Yep, no flaws in the pathfinding with my Autodrive anymore.

Why the goto function making ped ALWAYS turn to north?
