How to create a Skill Tree and related elements

Here’s a simplified and clearer version of your explanation for creating a skill tree in MCreator. It focuses on making it straightforward and easy to follow:

How to Make a Skill Tree in MCreator

Let’s create a basic skill tree with two branches: Strength and Resistance. Players will use their experience levels to unlock skills. For simplicity, each branch will have 4 skill levels: I, II, III, IV

Step 1: Create the GUI for the Skill Tree

1. Open the GUI Editor in MCreator:
   • Create a new GUI for the skill tree
   • Set up a background image for the GUI (optional, but it helps visually)
2. Add Skill Icons:
   • Create icons for each skill level: one for the locked version and one for the unlocked version.
   • Place the locked version directly over the unlocked version (we’ll control their visibility using procedures)
3. Add Buttons:
   • Place buttons for each skill. Each button will be linked to a procedure to handle unlocking and effects
4. Keybind to Open the GUI:
   • Create a keybind in MCreator that opens the skill tree GUI when pressed

Step 2: Set Up Procedures for Skill Unlocking

Yeppi !! Procedure Time :)

1. Create Boolean Variables for Skills

• Go to Global Variables and create a Boolean variable for each skill (e.g., Skill_Strength_I, Skill_Resistance_I, etc.)
• Default each variable to False (locked)

2. Handle Skill Unlock Logic

• Attach a procedure to each skill button. This procedure will:
  1. Check if the player has enough EXP:
     • Check if the player has sufficient EXP to unlock the skill.
  2. Unlock the Skill:
     • If the player has enough EXP:
       • Set the skill's Boolean variable to True
       • Deduct the required EXP from the player
       • Display the unlocked icon by hiding the locked one
     • If not, display a message: You don't have enough EXP!

3. Add Effects for Unlocked Skills

• For simplicity, when a skill is unlocked:
  • For Strength skills: Add a Strength potion effect to the player, increasing its level with each skill
  • For Resistance skills: Add a Resistance potion effect similarly
• You can use the Add Potion Effect block in procedures to handle this

Step 3: Display Unlocked/Locked Icons

• Use a procedure to control icon visibility:
  • If the skill’s Boolean is False (locked): Show the locked version
  • If the skill’s Boolean is True (unlocked): Show the unlocked version

Optional: Using Skill Points Instead of EXP

If you want to use skill points:

• Create a Global Numeric Variable for skill points
• Adjust the procedures to deduct skill points instead of EXP when unlocking skills
• Note: You will need to create a system for gaining skill points based on your mod's mechanics

Tell me if you have any other question :)

First question : Yes

Second question :

You will have this when adding the skill icon to gui change always to your condition

Create a Procedure that has

if Skill_Resistance_I = true

    return true

return false

then attach it to that

np, if you need anything else just ask :)
