C++ (Cpp) vec3_t::Length Examples

Example #1

File: eff_all.cpp Project: vermagav/mechmod

vec3_t CPartEffects::RandomRoundVec( vec3_t vMin, vec3_t vMax )
{
	float flMin, flMax;

	flMin = vMin.Length( );
	flMax = vMax.Length( );

	vec3_t vVec( gEngfuncs.pfnRandomFloat( vMin.x, vMax.x ), gEngfuncs.pfnRandomFloat( vMin.y, vMax.y ),
		gEngfuncs.pfnRandomFloat( vMin.z, vMax.z ) );
	vVec = vVec.Normalize( ) * gEngfuncs.pfnRandomFloat( flMin, flMax );

	return vVec;
}
