Difference between object on scene and pooled object

Hello
I've a question about optimisation. Is there any difference in optimisation/memory between object that I put on scene and set SetActive(false) and from a pooled one instantiated by a script and also SetActive(false).

 

There's no difference; an object gets instantiated in the scene, it will create an allocation call and have a reference in memory.

The purpose of object pooling is to save on rapid allocation calls for frequently used objects, by instantiating a number of objects all at once, getting all the allocation calls out of the way, and re-using them.

 

thanks for the information

 

Object pooling is a performance optimization, not a memory optimization. Calling SetActive is faster than calling Instantiate, basically.
