Roblox Studio
Your mission: Open a door when coins are enough (demo uses a NumberValue).
⏱ 15–25 min · Skills: Studio · events · loops
Step 1 — Understand
1 min
Do this
- Look at the finished Door System idea.
- Read your mission.
Why? Seeing the goal first makes Studio steps clearer.
Check: I know what success looks like.
Step 2 — Build in Explorer
2 min
Do this
- Open Explorer.
- Create the Parts named in the instructions.
- Turn Anchored on when needed.
Why? Without Anchored, Parts can fall when you press Play.
Check: Part → Script
Step 3 — Add the Script
3 min
Do this
- Insert a Script in the correct place.
- Paste the starter code.
- Read each line once.
Why? script.Parent tells the Script which object to control.
local door = script.Parent
local coins = 100 -- demo; replace with real data later
if coins >= 50 then
door.CanCollide = false
door.Transparency = 0.5
print("Door opened")
else
print("Need more coins")
end
Click a line below to highlight the concept (simulation).
Select a line to see what it does.
Place this Script where the project steps say. Use Explorer + Properties. This page is not Roblox Studio.
Press Play in Studio, open Output, and verify the mission behavior.
Step 4 — Test

Do this
- Press Play.
- Open Output.
- Verify the behavior.
Why? Output shows prints and errors immediately.
Step 5 — Modify
2 min
Do this
- Change one number or message.
- Playtest again.
Why? Small changes prove you understand the code.
Step 6 — Challenge
3 min
