Learning how to program visual effects

I am trying to learn how to program visual effects using Trails, ParticleEmmittors and all that. But I have gotten nowhere. Are there any tutorials I can refer to?

If your looking to specifically learn about trails and particle emitters you should review the API Reference.
https://developer.roblox.com/en-us/api-reference/class/ParticleEmitter

That’s the first place I went to, but I do not feel satisfied…

I mean the official ROBLOX API guide is the main guide so I don’t think there’s a resource that will be more detailed then that. But if your looking for a tutorial AlvinBlox or DevKing are great ROBLOX programming YouTubers you can try to see if they have a tutorial on what your looking for.
