Obstacle *obstacles_A[]

Obstacle *obstacles_A[]

This is incorrect - it doesn't carry the dimensions of the array and you probably trash your stack or something like that.

You should definitely use a vector or a list:

QList<Obstacle*> obstacles;
obstacles << new Obstacle(...);
//or
obstacles.resize(10);
obstacles[7] = new Obstacle(...);

QList<Obstacle*> obstacles;
obstacles << new Obstacle(...);
//or
obstacles.resize(10);
obstacles[7] = new Obstacle(...);
