Possible bug with velocity test and object bind

[devailo]

Hello, not to start a new topic but i have a similar problem. I have moving objects and have some particles bound on them. I want new particles to start spawning when the objects stop moving. So i guess this is velocity magnitute equals 0 ? yes but it does not work. it either spawns particles all the time or no particles at all depending on the tests i do. Any suggestions?
