GPS plugin -> callback is not called - Patchwerk - 02.02.2013

Hi, i have problem. My code

Code:

public OnPlayerClosestNodeIDChange(playerid,old_NodeID,new_NodeID){
new strr[128];
format(strr,128,"Old %d New %d",old_NodeID,new_NodeID);
SendClientMessageToAll(-1,strr);
return true;
}

this public is not called... how to repair this ?

Thanks

Re: GPS plugin -> callback is not called - Gamer_Z - 02.02.2013

did you use gps_AddPlayer(playerid); for the player you want to use the public for?
and remember to use gps_RemovePlayer(playerid); when not needed anymore.

There is a extended tutorial on the GPS plugin available here: https://sampforum.blast.hk/showthread.php?tid=411357

Thanks, it works !

Thanks for fast reply.

AddNode(Ex).

Re: GPS plugin -> callback is not called - Patchwerk - 03.02.2013

I have this

Code:

print("1");
new car = GetPlayerVehicleID(playerid);
node++;
new Float:x,Float:y,Float:z;
print("2");
GetVehiclePos(car,x,y,z);
print("3");
AddNode(x,y,z,1, 1);
new str[256];
format(str,256,"node %d",node);
print("4");
CreateDynamic3DTextLabel(str, 0xFF0000FF, x, y, z+5,50);
print("5");

In 1 second timer and its crashing my server. In serverlog i have last print "3"

Re: GPS plugin -> callback is not called - Gamer_Z - 03.02.2013

I suggest you leave out the 1,1 after the xyz paramaters and use RebuildGraph (plugin and include version 184) after you are done adding nodes.

Re: GPS plugin -> callback is not called - Patchwerk - 04.02.2013

How to use it ? Can you make example usage ?

Re: GPS plugin -> callback is not called - Gamer_Z - 04.02.2013

pawn Code:

//example for RebuildGraph
#include <a_samp>
#include <RouteConnector>

#define MY_NODES (5)

new Float:ArrayWithPositions[MY_NODES][3] =
{
    {0.0,0.0,0.0},
    {1.0,1.0,1.0},
    {2.0,2.0,2.0},
    {3.0,3.0,3.0},
    {4.0,4.0,4.0}
};

new SavedNodeIDS[MY_NODES];

new Errors[2] = {0,0};

public OnFilterScriptInit()
{
    //create nodes
    for(new index = 0; index < MY_NODES; ++index)
    {
        SavedNodeIDS[index] = AddNode(ArrayWithPositions[index][0],ArrayWithPositions[index][1],ArrayWithPositions[index][2]);
        if(SavedNodeIDS[index] == (-1))
        {
            ++Errors[0];
        }
    }
    //connect nodes
    for(new index = 1; index < MY_NODES; ++index)
    {
        if(SavedNodeIDS[index-1] != (-1) && SavedNodeIDS[index] != (-1))
        {
            if(ConnectNodes(SavedNodeIDS[index-1],SavedNodeIDS[index]) < 0)
            {
                ++Errors[1];
            }
        }
    }
    //rebuild graph
    if(RebuildGraph())//server freezes until graph is rebuild, should take a few miliseconds
    {
        if(Errors[0] || Errors[1])
        {
            printf("Graph rebuilded succesfully but failed adding %d nodes and failed to create %d connections.",Errors[0],Errors[1]);
        }
        else
        {
            printf("Graph rebuilded succesfully without errors.");
        }
    }
    else
    {
        if(Errors[0] || Errors[1])
        {
            printf("Graph rebuild FAILED, %d nodes could not be added and creating %d connections failed.",Errors[0],Errors[1]);
        }
        else
        {
            printf("Graph rebuild FAILED but all nodes were added succesfully.");
        }
    }
    return 1;
}

Re: GPS plugin -> callback is not called - Patchwerk - 04.02.2013

Thanks its useful function

Re: GPS plugin -> callback is not called - Gamer_Z - 04.02.2013

Also note that RebuildGraph() takes care of race conditions (threading problems) while AddNode with AddToPathfinder = 1 set does not.

Re: GPS plugin -> callback is not called - Patchwerk - 09.02.2013

I have this

Code:

	new File:f = fopen("Nodes.txt",io_read);
	    print("2");
	new str[256];
	new indexx;
	while(fread(f,str)){
	    new Float:x,Float:y,Float:z;
        sscanf(str, "p<|>fff", x, y, z); //sscanf plugin :)
  //  	printf("%f %f %f",x, y, z);
        SavedNodeIDS[indexx] = AddNode(x, y, z);
        if(SavedNodeIDS[indexx] == (-1))
        {
    	print("ERROR");
            ++Errors[0];
        }
        indexx++;
    }
    fclose(f);
	    print("4");
    //connect nodes
    for(new index = 1; index < MY_NODES; ++index)
    {
        if(SavedNodeIDS[index-1] != (-1) && SavedNodeIDS[index] != (-1))
        {
            if(ConnectNodes(SavedNodeIDS[index-1],SavedNodeIDS[index]) < 0)
            {
    	print("ERROR 2");
                ++Errors[1];
            }
        }
    }
    print("creating graph !!!!!!!!!!!");
    //rebuild graph
    if(RebuildGraph())//server freezes until graph is rebuild, should take a few miliseconds
    {
        if(Errors[0] || Errors[1])
        {
            printf("Graph rebuilded succesfully but failed adding %d nodes and failed to create %d connections.",Errors[0],Errors[1]);
        }
        else
        {
            printf("Graph rebuilded succesfully without errors.");
        }
    }
    else
    {
        if(Errors[0] || Errors[1])
        {
            printf("Graph rebuild FAILED, %d nodes could not be added and creating %d connections failed.",Errors[0],Errors[1]);
        }
        else
        {
            printf("Graph rebuild FAILED but all nodes were added succesfully.");
        }
    }

but its print "Graph rebuild FAILED but all nodes were added succesfully."

that is weird : o does CalculatePath calculate with the new nodes?

Re: GPS plugin -> callback is not called - Patchwerk - 09.02.2013

Yes, i can use CalculatePath with new nodes

Re: GPS plugin -> callback is not called - Patchwerk - 09.02.2013

sorry, im not tested it

Re: GPS plugin -> callback is not called - Patchwerk - 09.02.2013

No, it not working. It crashing my server

code

Code:

if(!strcmp("/3",cmdtext)){

			new nodeID = NearestPlayerNode(playerid);
			new nodeID2 = NearestNodeFromPoint(0,0,5);

		print("CalculatePath");
		CalculatePath(nodeID,nodeID2,playerid, .GrabNodePositions = true);
return 1;
}
