Deleting and spawning object
« on: March 29, 2018, 10:58:27 am »
How can i delete object when it passes the player and spawn new in the same time?

You can for example use a vector, then you can push and pop objects from it. Keep in mind that creating and removing object instances is basic C++ knowledge.

Make sure you use ht [code=cpp][/code] code tags next time you post code. :)
