[Solved] Shooting. Collision of the shot with a collection of List

[ad_1] Without claiming to rework your design, I added collection of dead invaders(ArmyOfInvaders.deadInvader) to stored those ones, who already shot, and changed InvaderGotShot and DrawItem methods.

You have 3 options: Don’t initialize output_list to have values. Let the program reserve space on the fly as you push_back. Don’t initialize output_list to have values, but increase its capacity using reserve. Initialize … Read more

[Solved] 2D array difference in C and C++

[ad_1] Arrays vs. pointers is probably one of the harder topics of C (and C++ which inherited that from C).
