Overview

The MEDS sample is a small Godot project that demonstrates how variables, events, bindings, and editor tools work together in a real scene.

If you want to see MEDS in action quickly, this is the best place to start.

What the sample shows

• resource-driven game state through .tres variables such as robot-health.tres, robot-rotation.tres, and robot-name.tres
• event-driven gameplay through samples/events/take-damage.tres
• UI bindings through variable-driven-label.gd, variable-driven-slider.gd, variable-driven-progress-bar.gd, bool-driven-checkbox.gd, and color-driven-color-picker.gd
• scene logic reacting to shared variables instead of relying on tightly coupled nodes
• debugger-friendly resources that can also be inspected with the MEDS editor tools

Main scenes

Scene	Purpose
samples/main.tscn	Main sample scene with the robot, menu, audio manager, and scene manager
samples/prefabs/menu.tscn	UI panel that edits and displays MEDS resources through bindings
samples/prefabs/player.tscn	Robot prefab and related listeners that react to variables and events
samples/game-over.tscn	Game over screen shown when the health variable reaches zero

Main resources

Resource	Role in the sample
samples/resources/robot-health.tres	Shared health state used by the robot, progress bar, heartbeat controller, and scene manager
samples/resources/damage-amount.tres	Amount removed from health each time damage is triggered
samples/resources/robot-rotation.tres	Rotation value controlled by the slider and applied to the robot
samples/resources/robot-visibility.tres	Boolean used to toggle whether the robot is visible
samples/resources/robot-name.tres	Text displayed in labels through variable-driven-label.gd
samples/resources/damage-color.tres	Color value used to tint the robot material
samples/events/take-damage.tres	Event raised by the UI button to trigger damage reactions

What to try in the sample

1. Toggle the checkbox to show or hide the robot.
2. Move the slider to rotate the robot.
3. Change the color picker to update the robot material.
4. Click Take Damage to raise the damage event.
5. Watch the progress bar, audio feedback, and scene transition react to the same shared resources.

Suggested reading order

1. Open samples/main.tscn to see the full sample scene.
2. Inspect samples/prefabs/menu.tscn to see how bindings connect UI controls to resources.
3. Inspect samples/prefabs/player.tscn and samples/scripts/robot.gd to see how gameplay reacts to MEDS events and variables.
4. Read the next page in this section for the full gameplay flow.
