The Meaning of Life, the Universe, and Everything.
So I'm in my world, doing my thing, and I try inputting this command into a command block: /particle magicCrit -786 139 602 -786 138 602 2 20 force. No matter how much I try it, the particles are not displaying, even though it gives me a confirming chat message and command block output that it worked. Any help? I'm sort of a novice when it comes to commands and redstone, so I'd very much appreciate help. If you want I'll provide a video explaining what I did.
Can you elaborate a bit what you mean by that? I'm not entirely sure I understand you.
/particle magicCrit -786 139 602 dx dy dz 2 20 force
dx/dy/dz are the number of blocks away from the listed coordinates that the particle should be played within in each direction. For example, setting dx to 1 would cause the area of effect to expand by 1 in each X direction (negative and positive). The values cannot be negative, but you can use decimals. Quick example of a small cube of particles:
