New example: Unit movement for tactical games

[D8H]

Hi!

I'd like to submit a new example to be added to GDevelop. Here is the link to

• download it: https://www.dropbox.com/s/tw7ipq4v6l9nf9e/tactical.zip?dl=1
• watch it: https://user-images.githubusercontent.com/2611977/117200816-33ed2a00-adec-11eb-90a8-91963989ff92.mp4
• try it: https://games.gdevelop-app.com/game-f415635d-f911-4817-8211-ecc5e7e2c7a9/index.html

I confirm that any assets can be used freely by anybody, including for commercial usage. I used Google icons that are free to use.

This example show how to

• move units the way most tactical games do:
  • highlight reachable cells for the selected unit
  • move the unit with a path finding movement behavior to go to the selected cell
• make a fog of war
• use a different path finding cost for each unit class (maritime, ground and air units)

This example use these extensions:

• An updated Linked Object Tool that add new conditions and a path finding movement behavior (https://github.com/4ian/GDevelop-extensions/issues/140)
• A variable copier to copy structure variables (https://github.com/4ian/GDevelop-extensions/issues/139)

Hi, The example looks and works great!

I did find an unused yellowselection.png file

Other than that it's all great and I didn't find any other issues

Thanks for the review.

Is it a strong rule to use every asset? I left it on purpose as an invitation for users to try things with it. I think one goal of the examples is to let users experiment new features. It would be sad if they are stopped by missing assets.

It does make sense. But, having something that doesn't have any use out of the box is weird. Many people would be happy to just scribble a new object using piskel for experimenting.If you really want people to use it, you can set it up as an object and inform the user that they can experiment with it.

I think you're right I removed it. I also extracted the grid linking to an action of the extension to allow to quickly link neighbors on a rectangular, hexagonal or isometric grid.

Hi, I forgot to include this issue I found :sweat_smile: , Maybe declare the scene variables, instead of declaring them in the event sheet?

• Another thing I found this time is a tiny spelling mistake, I think it is "if" and not "is"

:)

Very nice and well commented example. Thanks @Midhil457 for the review.

I went ahead and added the example in its current state :)
