Question
I’m making a generic projectile class and I have the Area2D hooked up to the area_entered signal for the player’s hitbox and body_entered for the tilemap. However, while it detects the player correctly, it does not detect the tiles at all, even though all the layers so far seem to be set up correctly. What am I doing wrong?
