Shapes and basic scripts in Roblox

Ball

To create a sphere in Roblox, you can use the Part object and set its Shape property to "Ball". Here’s an example of how you can do this:

local sphere = Instance.new("Part")
sphere.Shape = "Ball"
sphere.Size = Vector3.new(1, 1, 1) -- sets the size of the sphere
sphere.Parent = game.Workspace -- adds the sphere to the game world

This will create a sphere with a diameter of 1 unit and add it to the Workspace object. You can adjust the size of the sphere by changing the Size property, and you can also adjust its position and orientation by changing its CFrame property.

Person

To create a person in Roblox, you can use the Model object and add Humanoid and CharacterMesh objects to it. Here’s an example of how you can do this:

local character = Instance.new("Model")
character.Name = "Character"

local humanoid = Instance.new("Humanoid")
humanoid.Parent = character

local head = Instance.new("Part")
head.Name = "Head"
head.Size = Vector3.new(1, 1, 1)
head.Parent = character

local torso = Instance.new("Part")
torso.Name = "Torso"
torso.Size = Vector3.new(1, 2, 1)
torso.Parent = character

local lArm = Instance.new("Part")
lArm.Name = "Left Arm"
lArm.Size = Vector3.new(1, 2, 1)
lArm.Parent = character

local rArm = Instance.new("Part")
rArm.Name = "Right Arm"
rArm.Size = Vector3.new(1, 2, 1)
rArm.Parent = character

local lLeg = Instance.new("Part")
lLeg.Name = "Left Leg"
lLeg.Size = Vector3.new(1, 2, 1)
lLeg.Parent = character

local rLeg = Instance.new("Part")
rLeg.Name = "Right Leg"
rLeg.Size = Vector3.new(1, 2, 1)
rLeg.Parent = character

local characterMesh = Instance.new("CharacterMesh")
characterMesh.Parent = character

character.Parent = game.Workspace

This will create a character with a head, torso, arms, and legs, and add it to the Workspace object. You can adjust the size and shape of the parts by changing their Size and Shape properties. You can also add other objects to the character, such as a Hat, Shirt, or Pants, by creating them and setting their Parent property to the character model.

Enemy

To create an enemy in Roblox, you can use the Model object and add a Humanoid and CharacterMesh to it. You can then add a script to the enemy that controls its behavior, such as chasing the player or attacking when the player gets within a certain range.

Here’s an example of how you can create an enemy model and add a script to it:

-- create the enemy model
local enemy = Instance.new("Model")
enemy.Name = "Enemy"

local humanoid = Instance.new("Humanoid")
humanoid.Parent = enemy

local characterMesh = Instance.new("CharacterMesh")
characterMesh.Parent = enemy

-- add a script to the enemy that makes it chase the player
local script = Instance.new("Script")
script.Parent = enemy

script.Code = [[
    while true do
        -- find the player
        local player = game.Players:GetPlayerFromCharacter(script.Parent.Humanoid.Parent)
        
        -- move towards the player
        if player then
            script.Parent.Humanoid:MoveTo(player.Character.HumanoidRootPart.Position)
        end
        
        wait(1)
    end
]]

enemy.Parent = game.Workspace

This will create an enemy model with a Humanoid and CharacterMesh, and a script that makes it chase the player. You can adjust the enemy’s behavior by modifying the code in the script.

Here’s an example of how you can modify the script to make the enemy chase the player and jump around:

local enemy = Instance.new("Model")
enemy.Name = "Enemy"

local humanoid = Instance.new("Humanoid")
humanoid.Parent = enemy

local characterMesh = Instance.new("CharacterMesh")
characterMesh.Parent = enemy

local script = Instance.new("Script")
script.Parent = enemy

script.Code = [[
    while true do
        -- find the player
        local player = game.Players:GetPlayerFromCharacter(script.Parent.Humanoid.Parent)
        
        -- move towards the player and jump around
        if player then
            local toPlayer = player.Character.HumanoidRootPart.Position - script.Parent.HumanoidRootPart.Position
            local distance = toPlayer.Magnitude
            
            -- jump if the player is far away
            if distance > 10 then
                script.Parent.Humanoid.Jump = true
            end
            
            script.Parent.Humanoid:MoveTo(player.Character.HumanoidRootPart.Position)
        end
        
        wait(1)
    end
]]

enemy.Parent = game.Workspace

This script will make the enemy chase the player and jump around if the player is more than 10 units away. You can adjust the distance at which the enemy starts jumping by changing the value of distance.
