  • In Is it possible to access the class from the packedscene?

    Thanks for the suggestions. Whilst GetNodeType did work, it still left me with having to pass in a string rather than a class. I'll stick to creating multiple scenes and attaching them to an exported variable on the tank.

  • In Is it possible to access the class from the packedscene?

    If I pass bullet.tscn into another method, can I derive the class (i.e. bullet.cs) from the PackedScene in order to access the properties and methods on the class?

  • In Why can I pass 1 param but not 2 in my signal?

    This was a classic example of PICNIC syndrome: Problem In Chair Not In Computer!

    I had declared the Shoot method in 2 different places and the code was calling the one with a single arguement signature first because it was higher in the scene tree. (I think scene tree is the right phrase)

  • In Why can I pass 1 param but not 2 in my signal?

    My signal is connected in the code using: _enemyBeige1.Connect("Shoot", this, "_on_Shoot");

    Then I emit it via EmitSignal("Shoot", "Fire!");

    This works fine except i want to pass 2 parameters through to _on_Shoot but I get Error calling method from signal Shoot.

    I did remember to update the _on_Shoot method to take 2 parameters. I've done this before in previous projects so I know it is possible but I just can't make this work.

    Also, what is the benefit of declaring the params/arguements when declaring the signal? [Signal] delegate void Shoot(string p1, string p2);

    Do you need the background to register the event? If not, you could just remove the code.

  • In click n drag arrow to select destination square

    I toyed with going the GDScript route as I'm a huge Python fan but I use C# in my daily job and figured it would be best to stick with something I already know vs trying to learn something new.

  • In Odd sprite issues with rotation and offset

    So regardless of the rotational transform displayed, the origin doesn't change?

    Why would the need to do the offset in Y vs X change though?

    Actually I kinda gave up on the arrow idea and just drag the tank sprite for the time being. Seems simpler to implement.

  • In Odd sprite issues with rotation and offset

    i've run into an odd issue with sprites and rotating them. The Kenney tank sprites all point downwards and so need rotating 90 to face Godot's 0 degrees. No big deal. However, this played havoc with my code that rotates the barrel. I then remembered in a @KidsCanCode tutorial he said he pre-rotated them. I switched to those assets and bingo, no wierd rotation issues. so 2 questsons: 1. why does the starting rotation impact code to rotate to a given position? It seemed to be 90 degrees off each time (visually speaking as the the calc is in radians) 2. in the unrotated assets I had to set the offset in X whereas in the rotated ones I had to set it in Y to get it in the same starting position. This one is really confusing. I guess I could correct the rotation calc to allow for 90 but i don't understand why I would need to
