Hi, I'm writing a vec4 math struct and I have a method of which the
return value has to be a lvalue so I wonder which is the correct way to
do this:
vec4 Normalize() const { ... } //won't work, not a lvalue
ref vec4 Normalize() const {
vec4 temp;
...
return temp;
} //will this lead to a segfault or not?
ref vec4 Normalize() const {
vec4* temp = new vec4;
...
return *temp;
} //ugly, don't want to allocate anything on the heap
auto ref vec4 Normalize() const {
vec4 temp;
...
return temp;
} //will this lead to a segfault?
Or do I need to do it totaly in some other way?
If you need to normalize vector inplace, then your Normalize() shouldn't
be const:
ref vec4 Normalize() {
// code
return this;
}
If you want to return a normalized copy of vector, the you don't need ref:
vec4 Normalize() const {
vec4 temp;
//...
return temp;
}
