Regarding Graphics and Performance?

Is this true :

"Turn off collisions on objects that don't need them"

Would it not be quicker, easier and more...... educational to simply try it and see what happens?

While we're on sprite objects, if I create a blank (making it invisible) sprite so that an event occurs if a player clicks on it, how much space [& resources] does it use compared to a graphically full sprite?

And is there a better way to do this?

Well, if an object is invisible (not 0 opacity, has to be properly invisible) it doesn't make draw calls. Also, if you turn collisions off -- and you have to do that, they default to 'on' -- that lowers your overhead.

Even if you aren't testing for collisions with a particular object, just having collisions on can eat up a significant amount of overhead.

How can i know if i have ton's of objects, particles and sound files !!!

No, it's not true. As of r161 objects which don't have any collisions tested against them do no collision-related work at all, so the option has no effect if you already don't test for collisions on that object.

Even before then it would have made such a tiny difference as to be unlikely to be measurable. As with any performance question, measurement is king: if you cannot measure a performance difference, it either does not affect performance, or has such a small effect as to be ignorable.

Everything likely to affect performance has already been listed in Performance tips. Anything not in that page is not generally something that has a significant effect.
