Hello, I am buildig my first game in Godot. It is a platformer game where the player can die either:
- When the timer reach 0 seconds
- When he touches spikes in the level
For the timer, I am just sending a signal to the player when the timeout happen
However, I don't know what to do for when the player touches the spikes. There are many ways to achieve what I want. They all work but Idk which one is the best practice in terms of game dev with godot.
1. In Spikes.cs , when the player enter in the Area3D, I use:
public void OnBodyEntered(Node3D body)
{
if (body.HasMethod("Die"))
{
body.Call("Die");
}
}
Not a huge fan of this one since it seems to be using reflection. A better version I found:
public void OnBodyEntered(Node3D body)
{
if (body is player player)
{
player.Die();
}
}
This one seems to be the best version so far.
2. Event bus
It was a bit hard to create in C# since most tutorials are doing it using godot but I managed to make it work. This way is good but the player needs to subscribe/unsubscribe to a global script which creates a strong dependency between the player and a singleton. So it will be harder to tests and every time I change/reload a scene, I must make sure the player unsubscribe.
3. Connect through scripts
The thrid one attempt was to connect with scripts. So basically, on the OnReady method of the Spike.cs, I find the player and create the same setup as the timer. I just do this using scripts because they will be a lot of spikes in the level.
4. Detect collision in the Character.cs
If I do this, I only have one script running checking for collision instead of multiple one. However, I did not find the signal OnBodyEnteredOnBodyEntered in the editor for the CharacterBody3d. Plus player hitbox can change when the player crouch so it complicates things.
I would appreciate some guidelines here please
