Garbage Collection friendly code

Development Discussion C++ Programming
#1

Hello guys,

I posted another thread on the AnswerHub, where my exact problem is stated: My Post
Looks like I found the problem myself though, as the Garbage Collection seems to give me huge hitches. In my game I have fast-firing weapons though, what causes a lot of projectiles to spawn and despawn subsequently. I guess that is not what one would call “Garbage-Collection-friendly”? How can I avoid the huge hitches every 30-60 seconds?
In the UE3 docs/forums I found some posts about turning the GC Verify off to avoid hitches, but I guess there’s a reason for it to be there? Is that even possible anymore in the UE4?
I am thankful for any help! Thanks in advance :slight_smile:

Best regards,
Nanoxin

Necroing thread. Still there is no legit info how to optimize your GC

For short lived, transient objects, of which there are many (such as projectiles or particles) - the usual answer is spawn a fixed number of them and reuse instead of creating/destroying.
