How do I...?

As we developed the tutorials and learned Lua in the process we discovered a number of useful techniques. We kept them as a handy reference for future projects.

• Animate a character depending on the direction of movement.
• Countdown timer.
• Files: commands to read data from files.
• Fonts: how to display text on-screen, font files and creating a font.
• Interfaces: how to build multiple screens, maps and levels.
  • Part 1 - how interfaces work in Defold;
  • Part 2 - creating a controller collection and script;
  • Part 3 - how to send a message to the controller script;
  • Part 4 - Building UI elements with GUI and GUI scripts.
• Iterations: popping all items from a table.
• Objects: giving them a time to live.
• Objects: rotating sprites without using an animation set.
• Particle FX: render particles behind other game objects.
• Sounds: how to play sound effects and music.
• Tilemap collisions.
