2023 - Great optimizations tricks - thank you!

[@roelzwakman9641]

Although a lot of the other tips are good, I'd like to add a bit of a correction to the first tip. When you handle a lot of destroying of particle systems in your game, it's probably a better idea to use an object pooling system. You add these particle systems' GameObjects to a list of GameObjects, and instead of destroying and instantiating the particle systems, you disable them, reset their variables to the wanted start variables, and instead of instead of instantiating a new GameObject, you re-enable one of the ParticleSystems. This improves your performance almost every time you use it, with some exceptions like not having very many particle systems.

[@GabrielAguiarProd]

Thank you Roel, it's true. Forgot to mention that. Even tho it really depends on the situation, it's worth mentioning pooling methods to minimize instantiation. Recycling can help performance when dealing with hundreds and hundreds of objects that are going to be instantiated a lot.

[@jonavuka]

It all depends, pooling can hurt performance too so it's situational

[@Sparrow420]

Unless it's a complex system that needs to play over time i don't even do that. What I do is just keep one instance, where ever it needs to be played i just move it there and call .Emit on the particle system, that works great for a bullet impact in a shooter for example.

[@Clavus]

There's one veeeeery important performance pitfall with particle systems you're forgetting: overdraw. When you have even just a small amount of particles that fill up your camera view, your GPU has to redraw many pixels multiple times, causing significant framedrops if you're not careful. Not an uncommon problem for when you have smoke / explosion effects.

[@GabrielAguiarProd]

Indeed. This is very true. Well put Clavus, thank you.

[@ogireis3246]

whats the solution for this?

[@bpro5848]

​@@ogireis3246fr!! What is it?

[@P0Omah]

Fucking hell dude, the amount of quality content you put out for free is amazing.

[@GabrielAguiarProd]

Thanks man!

[@YimboSlyce]

Thank you! my games fps improved by +15!

[@GabrielAguiarProd]

That's nice man! Well done.

[@SachaSilva-is6kn]

would it be possible to make a video like this, but using UE5?

[@Endar0]

These are some very helpful tips. Thank you!

[@seworian2185]

Thank you so much for making this! your tutorials are very clear and understandable

[@zankaster3935]

Thank you for all the useful information

[@HaganeKen3d]

Thanks for the video, these tips helps a lot. I have a question, instead destroy the Game Object. it's also perform used the function SetActive? Thanks

[@GabrielAguiarProd]

Yes you can! It's even more recommended than destroying :)

[@Rubidev]

I am sure you know more than this to share about performance. Please do explain the most performant way to evade "GetComponenet"s and Instantiations. The emit on particle looks a bit tricky to me yet.

[@omeryilmaz1021]

what s the effect on the mobile of VFX graph instead of basic particle system?

[@rebekahobrien4517]

Thank you so much for making this!!

[@joy211191]

Probably late to the party but nevertheless. Instead of destroying the particle with a script, there is a "Stop Action" part which can be set to Destroy.

[@ricolafrogdamaster863]

Hey, I am getting into Unity Particle effects for a game aswell but I didnt spend much time in Unity yet. I notice that you always use quite a nice enviroment in your videos and I was woundering how I can quickly reproduce it to have a better sense of the effects I am creating. Thanks ahead Keep up the good work

[@Cybored.]

i would advise using the object pooling instead of Destroy if your doing it with a large amount of particles

[@GabrielAguiarProd]

Hi Ahmed, yeah someone already mention that in the comments, thank you. But it's mostly useful when instantiating hundreds and hundreds of effects/objects.

[@bulalaish]

great info. Thank you

[@sycopath7677]

Great video. But instead of destroying the particle system, wouldn't it be enough to simply stop the particle system by calling the ParticleSystem.Stop method?

[@ramalmaliki]

would you mind if you create black hole tutorial particle? for 2d game

[@GabrielAguiarProd]

Yeah maybe in a not so far future.

[@fangyechannel]

thanks for this tutorial , it is helpfule ~

[@GG1440]

Thank you

[@simonzhang3D]

3:06 is there a tutorial on this specific vfx?

[@TilSkywalker]

this is great! Xould you make a tutoril about water trails that a boat would lieave while driving through a river? Or some water efects in General :)

[@GabrielAguiarProd]

Thanks! Yeah in a not so far future there will be a tutorial about Ocean Water and Cartoonish Water as well!

[@idsamuel]

Wait what was that "Application Framerate = -1" ? First time hearing of it and can't seem to find anything on google.

[@GabrielAguiarProd]

"Application.tragetFramerate = -1" indicates that the game should render at the platform's default frame rate. If you set a value it means it will try to no go over that number.

[@idsamuel]

@@GabrielAguiarProd Ah okay, thanks!

[@skope2055]

high class

[@henriqueam]

Parabens pelo video. Mandei uma mensagem no patreon pra vc. Abraço.

[@Sparrow420]

About #1, what's why not just use the "StopAction" of the particle system?, you can just tell it to destroy itself when it's done, no need for those 2 get components with it's start.

[@GabrielAguiarProd]

It doesn't work sometimes. Specially if the particle system is attached to an empty gameobject that contains scripts or animations. Cheers.
