I am a newbie in unity and have not much experience in scripting.
I have modeled an octopus using maya, and imported into unity.
I wanted to have the octopus to spit ink when the first person controller approach it.
I planned to do it with the triggered animation and a particle system.
Is that a good way to do it? How can create the physics of the liquid ink projected out powerfully?
Use GameObject > Create Other > Particle System to create your own. There are a ton of options and things to play around with though, and if it seems daunting, import the standard asset folder “Particles” and use some pre built ones, play with the settings on those to get different effects. You will notice they will often have different layers, so one layer could be big, slow moving white particles for smoke, with lots of small, faster moving particles in the middle for the fire. When I first used Unity particle systems, I took a standard fire particle system, and tweaked it until I got a nice, cartoon style, almost volumetric flame, blue in colour, that acted as the head of a character my friend was making. I had to make the speed and death rate quite high to keep the particles as close together as possible so the head didn’t become a long blue trail as the character walked around.
Basically, just play with it, particles can be fun! Just be sure to only use them when necessary, I have seen people instantiate one particle system after another, for rocket launchers etc, and if they are not properly killed, they will cause all sorts of problems, as they could be taking up valuable memory and processing power when you don’t need them any more.
