This project will create a point giving part that is constantly changing colors. Depending on what color the part is when touched, it’ll either award points to players or take them away. Blue will give players a few points, green will give a lot of points, and red will take away points. To set up the different conditions for each color of the part, you’ll create an if statement using elseif and else.
Setting up the Project
To setup this project, you’ll need a leaderboard and a part that changes colors.
Create a Leaderboard
On your own, create a leaderboard script to keep track of player points. If you haven’t created a Leaderboard before, learn how to create one with this tutorial.
Create the Part and Script
|0, 0, 255||Gives some points|
|0, 255, 0||Gives many points|
|255, 0, 0||Takes away points|
- Create an anchored part named PointPart with an attached script named PointScript.
- In PointScript, store the parent part in a variable.
- Set up the RGB value for blue, which will give players the least points.
blueand set it to
Color3.fromRGB(). To create a color, in the parenthesis, type
0, 0, 255, the RGB value for blue.
- Next, set up the green value
(0, 255, 0)and the red value
(255, 0, 0).
- Code variables for small and large amounts of points and a third for removing points.
Set Up the Script
Add the Players Service
To get to the player's information, add Players service to your script. Services are additional pre-built functions made by Roblox engineers to save you time. The Players service has a lot of helpful function for working with player information, like points.
local Players = game:GetService("Players")
Naming Service Variables
While other variables start lowercase, any service, like Players service, starts capitalized to let you know that variable is a service.
Set Up Touch and Points Functions
The part will need two functions. One function to give players points based on the current color of the part, the other to listen if a player touches the part.
- On the next line, create a new function named
givePoints()with a print statement for testing inside.
- Under that, create a second function named
partTouched()with a parameter named
- To find the name of the player that touched the part type:
- If a player touched the part, it’ll be stored inside the
playervariable. If not, then the variable will be empty. To award points, check if there is a player stored inside the
playervariable and if so, run
- Connect the function to the
pointPart's Touched event.
- Run the game and touch the part; you should see your test message.
- Check that the
game:GetService(“Players”)is capitalized and in quotations.
- Make sure that the Touched connection is at the bottom of the script.
Create Looping Colors
To loop through colors, the script will use a while true do loop that changes the part’s color every few seconds.
- At the end of the script, create a new
while true doloop.
Why Put the Loop at the Bottom?
while true do loop is not at the bottom of the script, any code below it will never be run. Since the while loop doesn’t stop, it’ll keep running the loop instead of any code below it.
