I have in a project a class Collision , and to make a more efficient detection, I wanted to have access to all instances (objects) of that same class. Is there any easy way to do this?
Edit 1
I did so: I created a class called world , which stores all objects and collisions, where I have the isColliding method, which checks the collision between one object and all others, or between two objects.
In order not to be left without a response record, I answer here what has already been answered in the comments and made by the OP: create a container with a pointer for all objects created, inserted at the time of construction. I suggest doing using a binary tree ( std::set ), to reduce complexity:
class Collision;
std::set<Collision> world;
class Collision {
public:
Collision() {
world.insert(this);
}
~Collision() {
world.erase(world.find(this));
}
}
This way you can find all Collision instantiated in your program.
