Hello, I've tried all the vectoral angles but I haven't been able to turn the rocket exactly where the player fired. I Need Some Help

float flVel1[3], flAng[3], flOrigin[3], flVel2[3];
			GetEntPropVector(entity_projectile, Prop_Send, "m_vecOrigin", flOrigin);
			GetEntPropVector(entity_projectile, Prop_Data, "m_angRotation", flAng);
			
			if(pTurnIt == 1)
			{
				flAng[0] = flAng[0]*0.0;
				flAng[1] = flAng[1]*180.0;
				flAng[2] = flAng[2]*0.0;
				PrintToChatAll("Projectile Turned");
			}
			
			GetAngleVectors(flAng, flVel2, NULL_VECTOR, NULL_VECTOR);
			
			
			flVel1[0] = flVel2[0]*1100.0; //Speed of a tf2 rocket.
			flVel1[1] = flVel2[1]*1100.0;
			flVel1[2] = flVel2[2]*1100.0;
			
			SetEntityGravity(entity_projectile, 1.0);
			TeleportEntity(entity_projectile, flOrigin, flAng, flVel1); //1100 vel speed

else
{
blah blah...
}

Tried This too but didnt worked

i am just giving my two cent. i personally never try but you may test negate the velocity value like so.

PHP Code:

float vecVelocity[3];
GetEntPropVector( rocket, Prop_Data, "m_vecVelocity", vecVelocity );
vecVelocity[0] *= -1.0;
vecVelocity[1] *= -1.0;
vecVelocity[2] *= -1.0;
SetEntPropVector( rocket, Prop_Data, "m_vecVelocity", vecVelocity ); 


you may also try

PHP Code:

TeleportEntity( rocket, NULL_VECTOR, NULL_VECTOR, vecVelocity);

To negate a vector you should use NegateVector.

If you want to rotate vectors to specific degree try this (took from SMLIB):

/**
 * Rotates a vector around its zero-point.
 * Note: As example you can rotate mins and maxs of an entity and then add its origin to mins and maxs to get its bounding box in relation to the world and its rotation.
 * When used with players use the following angle input:
 *   angles[0] = 0.0;
 *   angles[1] = 0.0;
 *   angles[2] = playerEyeAngles[1];
 *
 * @param vec 			Vector to rotate.
 * @param angles 		How to rotate the vector.
 * @param result		Output vector.
 * @noreturn
 */
stock void RotateVector(const float vec[3], const float angles[3], float result[3]) {
	float sinAlpha, sinBeta, sinGamma;
	float cosAlpha, cosBeta, cosGamma;

	{
		// First the angle/radiant calculations
		float rad[3];
		// I don't really know why, but the alpha, beta, gamma order of the angles are messed up...
		// 2 = xAxis
		// 0 = yAxis
		// 1 = zAxis
		rad[0] = DegToRad( angles[2] );
		rad[1] = DegToRad( angles[0] );
		rad[2] = DegToRad( angles[1] );

		// Pre-calc function calls
		cosAlpha = Cosine( rad[0] );
		sinAlpha = Sine( rad[0] );
		cosBeta  = Cosine( rad[1] );
		sinBeta  = Sine( rad[1] );
		cosGamma = Cosine( rad[2] );
		sinGamma = Sine( rad[2] );
	}

	// 3D rotation matrix for more information: http://en.wikipedia.org/wiki/Rotation_matrix#In_three_dimensions
	float x = vec[0], y = vec[1], z = vec[2];

	{
		float newX, newY, newZ;
		newY = ( cosAlpha * y ) - ( sinAlpha * z );
		newZ = ( cosAlpha * z ) + ( sinAlpha * y );
		y = newY;
		z = newZ;

		newX = ( cosBeta * x ) + ( sinBeta * z );
		newZ = ( cosBeta * z ) - ( sinBeta * x );
		x = newX;
		z = newZ;

		newX = ( cosGamma * x ) - ( sinGamma * y );
		newY = ( cosGamma * y ) + ( sinGamma * x );
		x = newX;
		y = newY;
	}

	// Store everything...
	result[0] = x;
	result[1] = y;
	result[2] = z;
}

Thanks, i wasn't know i can do with negate velocity value, (vecVelocity[1] *= -1.0; for Yaw so i should change that)
