STD problem?

I really don't know what's wrong with this code, and I can't find what's wrong with it.
I have

Code:

---

std::vector <Light_Point *> visible_pointlights;

---

and in a function I determine what lights are visible from the current position. Once that is determined what I do is

Code:

---

visible_pointlights.push_back(entities[i]->pointlight);

---

entities[i]->pointlight is a Light_Point too. Among some other data, Light_Point contains 3 floats called x, y and z. The problem is that the values in visible_pointlights[i] are not the same as entities[i]->pointlight.
I really don't know why it doesn't work because I'm pointing at the sime thing.
Also, in case you need to know entities[i].pointlight is defined as

Code:

---

Light_Point * pointlight;

---

I hope that helps determine what's wrong with my code.

Post the code that checks the element inside the vector container to that in entities array.

Sounds like there is an order problem.

Actually I'm just checking the values for entities[i]->pointlight and visible_pointlights to see if the values are right(in the Autos window of MSVS). So even if the the order was wrong, I should still see the same values. I'm really wondering why is it pointing to a wrong location.

I guess I'll have to rewrite the code in hopes that it works again.

That strange...What specific compiler error are you getting?

No, there is no compiler errror, everything compiles fine. But when I draw the lights I see the values are wrong, then I check out the values in the debugger and they are wrong, they are not the values that I'm supposed to get from visible_pointlights.push_back(entities[i]->pointlight) . The values of visible_pointlights are not the same as the ones in entities[i]->pointlight.

Posting more code is still probably the best way for someone to help you. Ideally, a small compilable example that illustrates your problem would be best. Otherwise, at lease show the functions that change the data in those data structures, as well as all the code that you are stepping through when you notice the incorrect values.

Also, using the debugger to step through the code should help you.

I must agree with jlou. Post more relevant code. Step through the code when you for the first time pushes to the vector and see it both values are the same. You are probably changing visible_pointlights or entities->pointlight values and not updating the corresponding datastructure. They must work synchronized or else it will not work. Remember that std::vector objects are stored as copies!
