Build larger Logic Bricks projects that remain organized, predictable, and easy to maintain.
Separate responsibilities
Keep each logic chain focused on one job. Movement, animation, audio, interface updates, and state changes are easier to test when they are not all placed in one long chain.
Use states and frames intentionally
Use states to control which logic is active at runtime. Use frames only to organize the graph visually. A frame does not enable, disable, or sequence the bricks inside it.
Plan variables before expanding the graph
Choose local variables for values owned by one object and global variables for values that truly need to be shared. Use clear names that describe the value rather than the brick that created it.
movement_speed
on a player object.
current_level
shared across scenes.
Keep timing and physics logic separate
Physics movement should remain in physics-focused chains. Animation, interface, audio, delays, and other timing-sensitive actions should be placed in separate chains when possible. This prevents timing-sensitive behavior from being forced into the physics update cycle.
Reuse proven graph patterns
Save templates for logic patterns you expect to use again, such as interaction prompts, health systems, camera behavior, or reusable movement controls. After loading a template, verify node paths, variables, groups, and state names before running it.
Use Script Controllers for focused extensions
When a behavior cannot be expressed cleanly with existing bricks, a Script Controller can bridge to a small custom module. Keep that module narrow in scope and treat it as an extension point rather than moving the entire system into one script.
