Stopping explosion from destroying character joints

Help and Feedback Scripting Support
#1

A weapon I’m using in my game is destroying the character joints on explosion, which is rather problematic as it can destroy the player’s right arm and make them unable to use any items, plus the items will be destroyed, and they are rather expensive in the game.

Of course this can be stopped by using DestroyJointRadiusPercent and setting it to 0, but the code of the weapon is more complex and I cannot repair it with my programming knowledge. Instead of a local explosion, where I would just need to type explosion.DestroyJointRadiusPercent = 0, the code looks like this instead:

Instance.new("Explosion", workspace).Position = rocket.Position
destroyRocket(rocket)

Is there any way to insert DestroyJointRadiusPercent into this type of script? I’ve been trying to search for help on the forum but I couldn’t find anything, and my attempts of repairing this were just causing errors.

I would really appreciate if someone could help me!

You can turn it into a variable and change properties:

local explosion = Instance.new("Explosion")
explosion.DestroyJointRadiusPercent = 0
explosion.Position = rocket.Position
explosion.Parent = workspace

The explosions are not destroying any character joints now, but the explosions deal no damage, since it was killing the player by breaking the character neck joint. I can repair this problem tho. Thank you!

A way to stop explosions from breaking Joins and welds, but take damage instead

Actually nevermind, I can’t figure out how to make the explosion deal any damage to the player as well, is there any value which is used to deal damage to the player, or do I have to start with a local?

Okay I figured how to repair the no damage problem, thank you again!

Hi, do you mind posting the code on how you were able to make an explosion that doesn’t destroy joints, deal damage? It’s necessary for me to know as well because I want players to be killed by the explosion but i don’t want any parts in the game to break including weapons. Thanks.

I am not fully sure if I correctly remember, but I think it was this script:
