Return projectile to launcher

[kimono]

Good evening, Openbor fans;
I'd like to return a projectile to its launcher.
The projectile will return in the opposite direction and may injure the enemy.

The change of direction and the candamage changes simply by attacking it.
This is how the knife entity is made up:

name        knife
health        1
type        none
shootnum     10
candamage     player obstacle
projectilehit 0
remove         0
shadow        0

Have you ever coded something like this?
I think @Kratus did something like this in SORX.

Will the knife flip direction when blocked by the player or when taking a hit?

Yes, this is correct: the knife flips direction when being attacked and candamage enemy

@kimono,

Something like I had going here?

• Flies a set distance, then reverses and returns.
• Reverses instantly if it hits an enemy.
• Can hit on the return - does NOT reverse if already returning.
• The owner is locked into waiting position until catching the return or hit by an enemy.

The boomerang weapon is an interesting idea; however, the scenario here would be that a knife is thrown, potentially damaging the player.
The player attacks the knife, which is thrown back in the opposite direction of its thrower and can injure them.
The knife originates from an enemy entity.
