Lesson plan

Introduction

Explain that students will be adding the core gameplay mechanics of the adventure game today: using a tool to collect items, selling items, and upgrading their spaces to collect more items.
Point out that this session will be heavy on guided tutorials. The next session will be more free-form, so students can work on their own or catch up.

Guided tutorial - Script game mechanics

Make sure all students have access to the starter tool.
Lead students through the following tutorials:

Wrap-up

Recap what students have created.
Optional - Ask students what feature they're excited to work on or add tomorrow as they finish their games.

Appendix

Troubleshooting and classroom tips

General troubleshooting

While students code, leave up example scripts for students to reference. The Tool script is especially helpful as it has nested if statements.
Check that students are indenting their code to look like the code samples. This makes code more readable and reduces the possibility of errors.

Scripting tips

Remind students to always add a comma between multiple parameters in a function, like in sellItems(playerItems, playerGold).
In the Upgrade script, the order of functions matters. Make sure that the function giveUpgrade() is above clickDetector.MouseClick.

Facilitation tips

To keep students on track, set a strict time limit for playtesting, like one minute.
Encourage students to remember a specific goal whenever playtesting, such as check if a tool harvests an item as intended. This helps them stay focused.

Customize the lesson

Expand the lesson

More than one item can be added to harvest, just remember that each item needs a BoolValue with CanHarvest set to true.
Surface GUI's, like the Upgrade Sign, can be customized. Encourage students to explore properties of TextLabels, like color and font in the properties of that TextLabel and SurfaceGui.
