Unity VFX Graph - Interactive Particles Effect Tutorial

Let's see how to create interactive particles in Unity! Quite useful for effects that need to interact with the player movement for example.

Love this one, the possibilities with this are pretty cool!

Wow! First time using VFX Graph from Unity 6 and my mind blows!🤯
So many new things. 😯
Wil be messy but amusing to learn the new stuffs. 😄
Thanks Gabriel for this and many more tutorials! I learned so many things thanks to you. 👍

I can't believe you made this tutorial I asked I think at the end of the 2023 ! Thank you ❤

If, like me, you are trying to complete this in a pre-unity 6 version (version 2022.3.9f for me), then you can still do it with these changes:

In the unity menu 'Edit > Preferences > Visual Effects' select the second checkbox titled 'Experimental Opperators/Blocks'.
This will allow you to add a 'Set Custom Attribute' block in the Update Particle section.

Notice (unlike me at first) that you get an inspector window when clicking on this block. Change the attribute name 'Attribute' to read 'DeformPosition'.

Now whenever Gabriel drags 'DeformPosition' from the attribute menu (which we don't have, we only have the properties blackboard) press space and add a 'Get Attribute: Custom' node. Click it and again, in the inspector, name it to be exactly the same as the set block (that is 'DeformPosition' again).

Thank you Gabriel for your excellent tutorials. I am also a big fan of your reactive shield tutorial: 'Unity VFX Graph - Shield Effect Tutorial'. If I every do finish a game it will look better because of your influence.

Hope this helps.

It's been a long time since I worked with the vfx graph. So much has changed! It looks really good now

[seanloughran]

I had no idea that Attribute table existed, let alone that you can create your own. So much great information!

Impressive content, Gabriel Aguiar Prod.. Looking forward to your next upload! I clicked the thumbs up icon on your video. Keep up the fantastic work. The way you demonstrated the particle interaction with the sphere was fascinating! Have you considered exploring how different shapes might affect the particles' behavior in future videos?

[GameBit]

Very good video. Thanks for creating this, Could you please create a CODM Gun effects?

[unknownBoylover]

It's so great thanks for it it will be better if you show volumetric ones like fog or smoke like one❤❤ thank you again and much appreciated 🙏

[johann]

Is it possible to have multiple affectors active simultaneously? Great video!

[citriccanine]

I have recently started watching and using these tutorials for my college work, really well made videos. Though i am curious what settings you use on your post processing global volume, i just cant get mine to look the same no matter what i try

[Silencewalker]

Is it possible to spawn grid particles along the complex geometry (colliders, terrain) without applying gravity to them?

[wurstohnedarm]

Hey Gabriel, this tutorial is amazing and exactly what i need. Everything works great but as soon as I press play the particles are flying away. Any idea how to fix that?
Thank you in advance!

[damonfedorick]

just saw a asset on sale in the store that had the same concept, only 5 mins ago.

[francoportepetit]

can you make particles have a sine wave motion?

[crysonstickleman]

for some reason, whenever I expose my sphere and reference it to a collider in the scene, there's an offset between the collider and where the particles are being effected (unity 2022)

[MidorayFire]

i'm wondering if i can i do something similar using only particle system since mobile devices dont support compute shaders that vfx graph use

[mikhailhumphries]

Vfx graph easy to understand but the difficulty comes with shader graph 😢

[jorgeelskizo]

have you stopped making tutorials for ue5?

I am using Unity 2022 and could never get the sphere to collide after converting to property. I came up with a work around. Add another variable that is a Transform and have it set to World. All others should be set to Local. Have this variable connect to Position on the Sphere. Add a VFX Property Binder for Transform. Use the Property name for you Transform and add your target. You can change the radius of the sphere on the graph.

Then I had a problem were you cant set the Target through code. I have multiple characters so needed a way to have the target be set for the current character. I ended up making a transform that all of the VFX use. Then on start I assign that as a child of the player and zero its local position.
