As the title says, How do you produce particle effects in Minecraft?
I am trying to create a 1x2 doorway filled with smoke particles. I would have a clock setup to keep reproducing these particles as well. My problem is, when creating the particle effect, the smoke lingers into a nearby corner. I however, as I stated, would like the particles to be stationary in a 1x2 door frame.
I am having trouble with one part of the command. I do not understand the "XD, "YD", and "ZD" part. What does this mean, and how would I use this section of the command? Is this what is making the particle linger into a corner, and not making it stationary?
