Summary:

Player projectiles now snap to block grid, instead of spawning at player position.

Impact:

Causes inconsistent projectile offsets, impacting the experience of players with no apparent way for us to fix.

Repro Steps:

1. Install the attached BP
2. Stand on the corner between 4 blocks
3. Shoot a projectile by running "/event entity @s x11:shoot_projectile" in chat (on maps this would be done by using an item)

Observed Results:

The projectile will spawn at the center of one of the 4 adjacent blocks, causing it to appear either to the right or the left hand side of the player.

Expected Results:

The projectile should spawn exactly at the player's eye position, at it did in the regression build.

Screenshots/Videos attached: Yes/No

Notes:

This seems to be related to the minecraft:spawn_entity component, which is used to spawn the projectile. The component is the only way to spawn player projectiles, since the summon command does not apply the aim direction.
