Hiya,

I would like to create a pacman using Felgo, I got the way to move the character and QML basics, but I couldn’t find a Felgo example where is related to a grid enabling some spaces to move and other like walls.

Thanks in advance.

Hi Charlie,
One way to do is to use Level Editor.
You can treat the “blocks/walls” as a normal element in your level editor, for example use Collider with Body.Static, and so on.
Search for platformer/level editor example, maybe it will help you.

For sure there are other ways to do it but this seems like a good place to look at.

I am not sure what perspective are you going to use, for example.
This decision can complicate your life a little 🙂

If you want more examples from Felgo, definitely Squaby demo is quite similar in many cases to Pac Mac.
The code is a little old and it is quite advanced so keep this in mind Squaby demo
Something much simpler that also uses grid approach is Juicy – like candy crush demo.

Game is quite different but there are plenty of grid calculations.

Hi Marcin thank you for your quick response,

actually I’m planning to create something more similar like this:

which is not that Grid approach.

I think I can create it step by step… For example, how can I “fire” something?

Thanks in Advance

Hi Charlie,

check out the CarChallenge demo, where we fire rockets in the direction the car is facing (space and enter button).

Cheers,
Alex

Thanks Alex, I could make it work by the following code:

 

import Felgo 3.0
import QtQuick 2.0
GameWindow{
    id:gameWindow
    Rectangle{
        id: background
        anchors.fill: parent
    }
    onSplashScreenFinished:{
        mov.running=true
        world.running=true
    }
    EntityManager{
        id:mng
        entityContainer: scene
    }
    Scene{

                entityType: "bullet"
                property int firingX:0
                property int firingY:0
