I don't know what the problem is. I tried readjusting the code, but I still get the error "Character is not part of DataModel." Here is the code:
Torso = game.Character.HumanoidRootPart
`Instance.new("ParticleEmitter", Torso)
local fire = game.Character.HumanoidRootPart.ParticleEmitter
fire.Enabled = true
fire.Texture = "rbxgameasset://Images/fire"
fire.Color = ColorSequence(255,0,0)
fire.Size = 3
fire.Lifetime = 1
fire.Rate = 10
fire.Speed = 1`
Please help me.

game.Characteris wrong. Character is not a child of game. The specific way you need to get the character depends on your situation.Okay thank you
