08: Extending the Platform

Learning Target

• Modify an existing GDevelop game 
• Duplicate objects to create new instances
• Add new objects to a GDevelop game

Instructions

Step 1: 

Open the GDevelop editor from the desktop or the Windows search bar. 

Step 2: 

If you keep saving games into your H: drive, it will become an extreme mess of overlapping projects and files. 

• • Go to your H: drive
  • Create a new folder for this course
  • Create a new folder inside this for each assignment

Always create new projects inside a new folder to avoid cross-contamination of game assets.

For example:

Step 3:

Turn on the Snap Grid. This will make it easier to move things precisely. You can turn it off at any time, if needed.

Step 4:

Let's extend the level. Move the right boundary further to the right. Don't worry about the exact distance.

Step 5:

Move the end of the level elements to the new edge of the level. 

Then, click on the background and resize it to fill the new scene boundaries.
This is a tiled sprite and so it will automatically draw new copies of itself.

Lastly, be sure to extend the top and bottom boundary sprites.

Step 6:

Extend the level by completing at least these steps:

• • Add 10+ new instances to the scene by dragging them from the Objects Panel.
    You can also copy-and-paste from those already in the scene if you prefer.

• • Be creative with your new objects. Don't just repeat patterns that already exist in the scene.

Step 7:

Save your game by pressing CTRL+S or using the File menu:

Step 8:

Test your game by using the Preview button that looks like this:

Notice that we saved your game first. You don't want to lose your work if the game crashes!

Step 9:

Make any changes that you think are needed. Then, save your project again. Repeat this process as needed.

Possible Extensions

Customize the game further by:

• • Adding new objects to the game 
  • Adding special effects
  • Changing behaviors of objects (save before doing this)
  • Creating a new level (advanced)
