Ever had the problem where you’re firing a bullet or some kind of projectile at high speeds, and it just goes right through the collision object, instead of hitting it?
Here’s a weapon that fires a bullet at random velocities, to demonstrate the issue:
The bullets impact the character in various places, rather than at the first point of contact. I haven’t found a way to enable any kind of continuous contact option, outside of playing with the
safe_margin
setting. I ended up adding a raycast:
It’s definitely a hack, though. The
move_and_collide
should be replaced by the ray query. Using both instructions together could result in an even weirder situation;
move_and_collide
could skip a collision object (the issue we’re trying to fix with the ray query), but then still collide with a different collision object. Then the ray query redoes the same movement and collides with the first object that was missed by
move_and_collide
. Depending on the game, that could mean something like randomly shooting through shields or walls under specific circumstances.
The current approach is essentially a two-pass solution, where the first pass is sloppy, and the second pass works as intended, but doesn’t move the projectile.
This release contains the new Godot editor integrations. It offers an Item Library bottom panel that makes it easier to manage your inventory item types, and an inspector plugin that lets you edit items in a GGItemCollection. This also reduces the need for manually creating GGItemData resources, which simplifies item management at design time significantly. …
This release finally uses Godot Engine 4.4. It adds the GGCraftingSystem singleton and updates the GGInteractable2DStrategyCrafting class to use it. The crafting editor nodes now have prefixes, which makes it much easier to search for specific recipe or item nodes in larger crafting libraries. Some syntactic sugar was added as well. You can now easily …
