Teleport an entity in front of a player?

Beaverboys · **Author**

I feel like this is some very basic trig that I can't figure out. I want to use a players origin and angles to teleport an entity 36 units in front of them. Could somebody provide some example code?

This is used by zprops

PHP Code:


			
AddInFrontOf(Float:vecOrigin[3], Float:vecAngle[3], units, Float:output[3])
{
    new Float:vecView[3];
    GetViewVector(vecAngle, vecView);
    
    output[0] = vecView[0] * units + vecOrigin[0];
    output[1] = vecView[1] * units + vecOrigin[1];
    output[2] = vecView[2] * units + vecOrigin[2];
}
 
GetViewVector(Float:vecAngle[3], Float:output[3])
{
    output[0] = Cosine(vecAngle[1] / (180 / FLOAT_PI));
    output[1] = Sine(vecAngle[1] / (180 / FLOAT_PI));
    output[2] = -Sine(vecAngle[0] / (180 / FLOAT_PI));
}

    output[1] = vecView[1] * units + vecOrigin[1];

    output[2] = vecView[2] * units + vecOrigin[2];

}

 

GetViewVector(Float:vecAngle[3], Float:output[3])

{

    output[0] = Cosine(vecAngle[1] / (180 / FLOAT_PI));

    output[1] = Sine(vecAngle[1] / (180 / FLOAT_PI));

    output[2] = -Sine(vecAngle[0] / (180 / FLOAT_PI));

}

better use this:

PHP Code:


			
stock void AddInFrontOf(float vecOrigin[3], float vecAngle[3], float units, float output[3])

{

    float vecAngVectors[3];

    vecAngVectors = vecAngle; //Don't change input

    GetAngleVectors(vecAngVectors, vecAngVectors, NULL_VECTOR, NULL_VECTOR);

    for (int i; i < 3; i++)

    output[i] = vecOrigin[i] + (vecAngVectors[i] * units);

}
