Mouse drag on specific area.

[heatblazer]

Hello, Im doing it again. Next game with another challenge for my 1 month Qt expirience. I have to make a train moving on the trails: https://www.flickr.com/photos/heatblazer/15453957743/ The picture shows the trails. The user must drag the train in the exact trails, no other space. Ive predefined invisible curves to match the rails so collision deteciton is OK. But this is the test picture, the final one will have a choice of the roads so I need to know what classes will I need. Just point me the way, I`ll to it on my own from there on.

Hi,

Sounds like you should either use the QGraphicsScene framework or QML

I am using QGraphicsScene. The queston is if there is an API to move the train on the rails with curves so if user drags up and there is a curved rail, the train must curve there too even the mouse is not.

If I can add invisible boundries, will the user be forced to curve to them? I wonder.

Makes me think of "collidesWithPath":http://doc.qt.io/qt-5/qgraphicsitem.html#collidesWithPath

Note that I haven't used it
