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.
A little while ago, I created a type of AudioManager to make it easier to work with sound files in bulk: Rather than assigning audio streams by hand, I was doing it programmatically; reading the contents of a directory and using load() to get the resources. It worked great and saved a lot of time …
This release improves weight management. Inventories can now configure an option weight limit, and item stacking and item transfer strategies are weight-aware. The crafting demo and crafting mechanic in the inventory tour have been improved. Auto-crafting is limited to the crafting slide, so that items don’t automatically and unexpectedly get crafted while stepping through the …
This inventory system release refines a lot of architecture guide sections based on customer feedback and adds over 100 additional pages to the PDF guide. Features: Bug fixes:
