I need to change a vector into an angle vector but don't know a formula to do this, and I'm pretty sure there isn't a function for SourceMod that does this yet (that I could find).

Here is the function for AMXX that worked:
vector_to_angle

You are going to need to use rectangular to polar coordinate conversions.

If you could be a little more specific in what you are doing I would be able to help you more.

I'm trying to make one entity face another entity.

Here is the code that will work if I can use that function:

PHP Code:

static Float:flClientOrigin[3], Float:flEntOrigin[3];
GetEntDataVector(iClient, g_offEntityOrigin, flClientOrigin);
GetEntDataVector(iEnt, g_offEntityOrigin, flEntOrigin);

static Float:flNewVec[3];
flNewVec[0] = flClientOrigin[0] - flEntOrigin[0];
flNewVec[1] = flClientOrigin[1] - flEntOrigin[1];
flNewVec[2] = flClientOrigin[2] - flEntOrigin[2];

static Float:flEntAngles[3];
// Here is where I need the function...
vector_to_angle(flNewVec, flEntAngles);

TeleportEntity(iEnt, NULL_VECTOR, flEntAngles, NULL_VECTOR);

This will turn the iEnt and make it face the iClient.

 
//Declare:
decl Float:flClientOrigin[3], Float:flEntOrigin[3], Float:flEntAngles[3];
 
//Initialize:
GetEntDataVector(iClient, g_offEntityOrigin, flClientOrigin);
GetEntDataVector(iEnt, g_offEntityOrigin, flEntOrigin);
GetClientAbsAngles(iClient, flEntAngles);
 
//Z Axis:
flEntAngles[1] = ArcTangent(flClientOrigin[1]/flClientOrigin[0]);
 
//Send:
TeleportEntity(iEnt, NULL_VECTOR, flEntAngles, NULL_VECTOR);

It should work fine assuming player angles in the mod your trying on uses the default QAngles, as shown here:

I just found GetVectorAngles()...

Pretty sure this is what I needed.

EDIT:
Just saw your latest post. Thanks for showing how to do it

No problem bro
