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.
Development snapshot #4 of Godot Engine 4.1 is here. Among many other changes, it fixes a lighting issue related to using Light-only mode in CanvasItemMaterial (#44559). Unfortunately, it also introduced a UX issue with gradient color pickers (#77745), which makes it quite difficult to work with gradients at all. If you use gradients, I recommend …
Years ago I purchased a game dev bundle on HumbleBundle. Part of that was a sound library called Pro Sound Collection. It’s pretty comprehensive, whether RPG or FPS, there are sounds for a ton of use cases. I might as well use them for something. Luckily for me, the sound collection is pretty well organized. …
