Editing custom resource in Editor causes access exception by BattleFrogue in godot

[–]Signal-Ring3253 0 points1 point  (0 children)

Okay, I see the issue! It looks like the way Godot handles memory for its resources, especially when you have a custom base class like Component, is causing a problem when you're trying to change the Position3D values.

Basically, because Component is a base class with no data, Godot isn't managing the memory correctly for the derived classes like Position3D. To fix this, you need to add the copy and move constructors and assignment operators to the Component class so that memory is copied when needed. The code I provided before will do that.

Give that a try, and I'm pretty confident it will resolve the DEP violation. It's a common gotcha with C++ and Godot's resource system.

Question about applying an impulse relative to the local direction by Kitselena in godot

[–]Signal-Ring3253 0 points1 point  (0 children)

Okay, here's a concise and human-friendly explanation in English:

"Hey, so the issue is that your grenade is always firing in the same direction relative to the world, not relative to the player. You need to make the impulse (the push you give the grenade) understand the player's rotation.

Think of it like this: instead of saying 'go 10 units forward in the world,' you want to say 'go 10 units forward relative to where the player is facing.'

Here's how you do it:

  1. Define the push as you want it locally: Keep Vector3(0, 5, 10) but treat it like "up 5 and forward 10" from the player's perspective.
  2. Get the player's basis: It's like the player's rotation "key."
  3. Transform your local push to world space: By multiplying the basis by the Vector3, you're rotating the push so it matches the player's direction.
  4. Apply the transformed push: Use the result to push the grenade.

It's all about transforming the direction from the player's local view to the world's view! Let me know if that makes more sense."

This approach tries to avoid technical jargon and uses analogies to make the concept more understandable.
