New example: City Builder

[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/6wwjfg75pyqm1qz/CityBuilder.zip?dl=1
• try it: https://games.gdevelop-app.com/game-143f99ba-13aa-4378-b1c3-50ce38efbb20/index.html

I confirm that any assets can be used freely by anybody, including for commercial usage.

It shows how to evaluate distance by roads to define rules for city builders.

This example use these extensions:

• an updated Linked Object Tool that allows to get the distance and combine several search to build complex rules (Updated extension: distance evaluation for Linked Object Tools GDevelopApp/GDevelop-extensions#144).
• the Isometry Helper to snap objects on a grid (New Extension: Isometry Helper GDevelopApp/GDevelop-extensions#102)
• the Mouse Movement without any change (New extension: Mouse movement conditions GDevelopApp/GDevelop-extensions#123)

Hi, I reviewed the project and it was great and it works great.

I did found some problems,

• There are some typos in the comments, I found some, but I think there are more
  Not sqares, neigborgs
  

• There is an empty events with only an condition

• I also suggest adding some comments just explaining what some parts do in simple terms. It took me a lot of time,to understanding some parts 😅

:)

Thanks for the review. I did the changes and did a pass on the typos.
Is it the part on the city evaluation that needs more explanations? (It's fresh in my mind so I may not see what could be hard to understand, but there is already long comments)

I had a hard time figuring out how links work in the game/extension or how exactly links get to the neighbours that is being searched. When a condition checks for at most 12 links, it doesn't explain how that number is calculated/checked. And also the cost system too. You could say, I didn't understand how the whole link objects extension works 😅

I see, it's hard to understand graphs on the fly if you have never used it before. I will prepare a wiki page for this extensions with diagrams.

Hi, I reviewed the project and I wasn't able to find any issues. I do have some suggestions

• Using a single object with animations representing the Palette Items instead of multiple objects added to a group. But, I wasn't able to fully making it work while testing. So, I am not sure if it is possible

• Also, as you have finished the wiki page, maybe you could include the link to the wiki so that people can learn how the linking system works. It could be helpful for someone who found it from the example list

It would need more events and be less intuitive in the instances editor. I don't mind having a lot of objects if it makes the events easier to understand.

Yes, I did it yesterday silently.

I wasn't able to find any comments that showed the wiki page's link. Did I miss it?

[D8H]

I thought you were talking of this:

It's true that's not the 1st thing that's used when reading a project. I added a note before the link action.

[Midhil457]

That's great! But, I did find it hard to find the comment where you have added it. It would have been more visible if you added it in a comment with more visible colours (something like green) As this example is centred around linking. It would make sense to add it at the top, but the current place is still fine. Also, it is "double" not "

Other than that, I didn’t find any other issues

Hi, If you are still interested in adding it to the library, you may open a issue in the new repo

:)

Right, thanks you, I opened this: GDevelopApp/GDevelop-examples#69
