\t\t\t\tI didn’t know this until today but Visual Studio has a built-in memory leak detector. One day out of the blue my game starts to take a long time to shut down and in the output window I see<\/p>\n
Followed by a bunch of numbers. <\/p>\n I looked it up today and after some research, I found out that the allocator counts memory allocations, and prints out the memory allocation number that caused the leak. I don’t know why in all the time I’ve been programming I’ve never heard about this before but it’s really useful!<\/p>\n This only works if your program state is repeatable (such as on startup) but it works really well from what I’ve seen.<\/p>\n All you have to do is put Somewhere at the top of your program.<\/p>\n Then either put at the start<\/p>\n or put at the end.<\/p>\n Lastly, to break at the specified allocation number, call<\/p>\n where X is the allocation number.<\/p>\n Alternatively, put this in your watch window:<\/p>\n It should show -1. Change that -1 to the number of the allocation.<\/p>\n For example:<\/p>\n I put F10 to step one line into my program.<\/p>\n I put {,,msvcr80d.dll}_crtBreakAlloc into the watch window.<\/p>\n I change the -1 to 614841.<\/p>\n I press F5 to run.<\/p>\n It should break when it hits this allocation.<\/p>\n I just fixed 2 leaks in about 5 minutes that I would have never found otherwise and only have 614,841 to go \ud83d\ude42\t\t<\/p>\n","protected":false},"excerpt":{"rendered":" I didn’t know this until today but Visual Studio has a built-in memory leak detector.
