[WellDone]

DeathOnaStick,
thanks, but

pawn Code:

new Float:pos[3],Float:Angle;
GetPlayerPos(i,pos[0],pos[1],pos[2]);
GetPlayerFacingAngle(i,Angle);
new const lesX = pos[0]; //2668
new const lesY = pos[1]; //2669
new const lesZ = pos[2]; //2670
new const lesA = Angle; //2671

and then

pawn Code:

SetPlayerPos(i,lesX,lesY,lesZ);
SetPlayerFacingAngle(i,lesA);

I'm getting

pawn Code:

and the game is starting to lag heavily when SetPlayerPos is called with this code and almost hangs my PC.

------------------------------------------------
The thing is that I'm trying to declare variables (or constants) equal to player's current coordinates and then, after changing player's coordinates a few times, set his coordinates back to those.
If I just declare variables equal to x, y, z, they're changing along with player's position and later, when player calls to SetPlayerPos, he teleports right to the same place where he's standing at the moment, not to his previous location...
