**APPLYING PRESETS TO YOUR EXPERIENCE LOGIC**
Presets will only add rules, variables and messages in and out. To create a fully working game mechanic you also need to add assets with behaviours and components to communicate with the Preset.
[See an example of applying a Ruleset for a **Collect Points** mechanic.](https://docs.sandbox.game/en/creator/game-maker/creative-guides/game-rules-guide/collect-points)
