Magnetic object SetPlayerVelocity? - Crystallize - 22.08.2017
So I've wrote up some messy code but I don't understand how SetPlayerVelocity works
PHP код:
#include <a_samp>
#include <foreach>
#define PRESSED(%0) \
(((newkeys & (%0)) == (%0)) && ((oldkeys & (%0)) != (%0)))
new Wreckball[MAX_PLAYERS];
new CountWreck[MAX_PLAYERS];
new Float:MoveToTargetX[MAX_PLAYERS];
new Float:MoveToTargetY[MAX_PLAYERS];
new Float:MoveToTargetZ[MAX_PLAYERS];
public OnFilterScriptExit()
{
for(new o = 0; o < MAX_PLAYERS; o++)
{
DestroyObject(Wreckball[o]);
}
return 1;
}
public OnPlayerDisconnect(playerid)
{
DestroyObject(Wreckball[playerid]);
return 1;
}
public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
if(PRESSED(KEY_FIRE))
{
if(CountWreck[playerid] == 0)
{
CountWreck[playerid] = 1;
new Float:X, Float:Y, Float:Z;
GetPlayerPos(playerid, X, Y, Z);
Wreckball[playerid] = CreateObject(18845, X, Y, Z+2, 0, 180, 0, 300);
GetPlayerCameraLookAt(playerid, X, Y, Z);
MoveToTargetX[playerid] = X;
MoveToTargetY[playerid] = Y;
MoveToTargetZ[playerid] = Z;
SetTimerEx("MoveFuckingObject", 750, 0, "i", playerid);
}
return 1;
}
return 1;
}
forward MoveFuckingObject(playerid);
public MoveFuckingObject(playerid)
{
MoveObject(Wreckball[playerid], MoveToTargetX[playerid], MoveToTargetY[playerid], MoveToTargetZ[playerid], 100.0, 0, 180, 0);
// foreach(Player,i)
{
// if(team[i] == TEAM_ZOMBIE)
// GetPlayerPos(i, X, Y, Z);
//GetXYInFrontOfPlayer(i, X, Y, 0.2);
// SetPlayerVelocity(i, 0.0, 0.0, 0.2);
}
return 1;
}
stock GetXYInFrontOfPlayer(playerid, &Float:x2, &Float:y2, Float:distance)
{
new Float:a;
GetPlayerPos(playerid, x2, y2, a);
GetPlayerFacingAngle(playerid, a);
x2 += (distance * floatsin(-a, degrees));
y2 += (distance * floatcos(-a, degrees));
}
stock GetXYBackOfPlayer(const playerid, &Float:x, &Float:y, const Float:distance)
{
new Float:a;
GetPlayerPos(playerid, x, y, a);
GetPlayerFacingAngle(playerid, a);
x -= (distance * floatsin(-a, degrees));
y -= (distance * floatcos(-a, degrees));
}
stock GetXYBackOfObject(const playerid, &Float:x, &Float:y, const Float:distance)
{
new Float:a;
GetPlayerFacingAngle(playerid, a);
x -= (distance * floatsin(-a, degrees));
y -= (distance * floatcos(-a, degrees));
}
stock GetXYRightOfPlayer(playerid, &Float:X, &Float:Y, Float:distance)
{
new Float:Angle;
GetPlayerFacingAngle(playerid, Angle); Angle -= 90.0;
X += floatmul(floatsin(-Angle, degrees), distance);
Y += floatmul(floatcos(-Angle, degrees), distance);
}
GetPlayerCameraLookAt(playerid, &Float:X, &Float:Y, &Float:Z)
{
new Float:Destination[3], Float:Camera[3], Float:Vector[3];
GetPlayerPos(playerid, Destination[0], Destination[1], Destination[2]);
GetPlayerCameraPos(playerid, Camera[0], Camera[1], Camera[2]);
GetPlayerCameraFrontVector(playerid, Vector[0], Vector[1], Vector[2]);
new Float: posAngle = atan2(floatsub(Destination[1],Camera[1]),floatsub(Destination[0],Camera[0]));
if(posAngle > 360) posAngle-=360; posAngle+=270; posAngle *= -1;
Destination[0] += 50.0 * floatsin(posAngle, degrees);
Destination[1] += 50.0 * floatcos(posAngle, degrees);
new Float:dis = floatsqroot((Camera[0] - Destination[0]) * (Camera[0] - Destination[0]) + (Camera[1] - Destination[1]) * (Camera[1] - Destination[1]) + (Camera[2] - Destination[2]) * (Camera[2] - Destination[2]));
X = Vector[0] * dis + Camera[0]; Y = Vector[1] * dis + Camera[1]; Z = Vector[2] * dis + Camera[2];
}
what I've tried (KEWL LOL)
PHP код:
forward MoveFuckingObject(playerid);
public MoveFuckingObject(playerid)
{
MoveObject(Wreckball[playerid], MoveToTargetX[playerid], MoveToTargetY[playerid], MoveToTargetZ[playerid], 100.0, 0, 180, 0);
// foreach(Player,i)
{
// if(team[i] == TEAM_ZOMBIE)
// GetPlayerPos(i, X, Y, Z);
//GetXYInFrontOfPlayer(i, X, Y, 0.2);
// SetPlayerVelocity(i, 0.0, 0.0, 0.2);
}
return 1;
}

I like the concept! I'll try to compile and run your function - perhaps when I get home, perhaps tomorrow (sorry gotta sleep and currently at work
) and see what's going on, unless someone already fixed it by then. I like the name of the function BTW.

Re: Magnetic object SetPlayerVelocity? - TheCman - 23.08.2017
Okay so I didn't run your code yet but from what I can see you're missing some extra trigonometry to calculate the velocity vector from the player to the ball, weighted by the (cubic root?) distance in between. I didn't have time to compile your code yet, let alone work on it, but will help you as soon as I get some free time.
