[Plugin] ColAndreas - Collision Detection

[CJ101]

For some reason the function CA_FindZ_For2DCoord(x,y,z); is not returning the ground Z level - its returning where the player IS.

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if (PRESSED(KEY_NO))
    {
        if(IsPlayerInAnyVehicle(playerid) && GetVehicleModel(GetPlayerVehicleID(playerid)) != 520) return 1;
        if(Players[playerid][carpetwait] == true) return GameTextForPlayer(playerid,"~r~Reloading...",800,3);
        new Float:x,Float:y,Float:z;
        GetPlayerPos(playerid,x,y,z);
        CA_FindZ_For2DCoord(x,y,z);
        CreateExplosion(x,y,z,11,3);
        CreateExplosion(x+3,y,z,11,3);
        CreateExplosion(x+6,y,z,11,3);
        CreateExplosion(x+8,y,z,11,3);
        Players[playerid][carpetwait] = true;
        SetTimerEx("CarpetAgain",12000,0,"d",playerid);
       
        new kill;
        for(new i = 0; i < MAX_PLAYERS; i++)
        {
            if(IsPlayerConnected(i) && IsPlayerInRangeOfPoint(i,3,x,y,z))
            {
                SetPlayerHealth(i,0);
                kill++;
            }
        }
        if(kill > 0)
        {
            format(xstring,sizeof xstring,"[*&*] Your airstike got you %d kills!",kill);
            SendClientMessage(playerid,COLOR_YELLOW,xstring);
            SetPlayerScore(playerid,Players[playerid][Kills] + kill);
            Players[playerid][Kills] += kill;
        }
    }
    return 1;
}

You are not checking if any collision is found!

cell AMX_NATIVE_CALL ColAndreasNatives::CA_RayCastLine(AMX *amx, cell *params)
{
	cell* addr[3];

	// Adding a small value prevents a potential crash if all values are the same
	btVector3 Start = btVector3(btScalar(amx_ctof(params[1]) + 0.00001), btScalar(amx_ctof(params[2]) + 0.00001), btScalar(amx_ctof(params[3]) + 0.00001));
	btVector3 End = btVector3(btScalar(amx_ctof(params[4])), btScalar(amx_ctof(params[5])), btScalar(amx_ctof(params[6])));
	btVector3 Result;
	uint16_t Model = 0;

	if (collisionWorld->performRayTest(Start, End, Result, Model))
	{
		//Get our adderesses for the last 3
		amx_GetAddr(amx, params[7], &addr[0]);
		amx_GetAddr(amx, params[8], &addr[1]);
		amx_GetAddr(amx, params[9], &addr[2]);

		*addr[0] = amx_ftoc(Result.getX());
		*addr[1] = amx_ftoc(Result.getY());
		*addr[2] = amx_ftoc(Result.getZ());

		return Model;
	}
	return 0;
}

If the raytest fails then your input x, y, z values remain the same.

One more person that didnt even bothered reading first post...You see if you did read you would know what to do, and you would't have to wait for a reply.

Use these version

Why am I getting "Pawno has stopped working.." whenever I try compiling with #include <colandreas>?
Those are my includes:

#include <a_samp>
#include <a_mysql>
#include <xml>
#include <streamer>
#include <colandreas>
#include <supporter>
#include <timerfix>
#include <sscanf2>
#include <Pawn.CMD>
#include <crashdetect>
#include <dialogs>
#include <log-plugin>
#include <YSF>

Allright, this is going to be weird.
Using colandreas_static.so CA_Init(); freezes my linux server. BUT it doesn't freeze if StrickenKid's MySQL plugin is loaded. I have no idea what's the connection between the two, but it's the only way to run ColAndreas for me.

Why are you using StrickenKid's MySQL plugin, I think it's outdated and not updated anymore.

[Amads]

I don't use it. Just without it loaded CA_Init(); freezes my server.

Great plugin, and it's better than MapAndreas
