How can i implement that code to get a position in right and forward from the player? Now i can get position just from the front

PHP Code:

#define FORWARD_DISTANCE 100.0

// Initialize vectors
static float vEntPosition[3]; static float vEntAngle[3]; 

// Gets the origin
....GetAbsOrigin(nEntity, vEntPosition);

// Gets the  eye angle
....GetEyeAngle(nEntity, vEntAngle);

// Calculate effect area origin
vEntPosition[0] = vEntPosition[0] + (FORWARD_DISTANCE * Cosine(DegToRad(vEntAngle[1])));
vEntPosition[1] = vEntPosition[1] + (FORWARD_DISTANCE * Sine(DegToRad(vEntAngle[1])));

You don't need to touch any sine or cosine for that. That's possible through the provided vector api. Have a look at GetAngleVectors, ScaleVector and AddVectors.

Is This what you're looking for?

PHP Code:

float fForward[3], fRight[3], fUp[3];
GetAngleVectors(vEntAngle, fForward, fRight, fUp);

vEntPosition[0] = vEntPosition[0] + fForward[0] * FORWARD_DISTANCE + fRight[0] * RIGHT_DISTANCE;
vEntPosition[1] = vEntPosition[1] + fForward[1] * FORWARD_DISTANCE + fRight[1] * RIGHT_DISTANCE;
