OSP Code Combat Grenades and Explosions (Originally by Beaver)

[ScreamingCommie]

Hi everyone, I don't know if this is worthy of its own topic, but here is a fixed version of Beaver's grenade script that has existed http://mbmodwiki.ollclan.eu/Grenade here for a long time. Thanks to the help of DuskVoyager, I have made a fixed version, that is also much more user friendly and modular. Note this is only tested in SP, but it could be converted to MP pretty easily.

An example grenade to put in your module_items.py

Whoa, didn't know ti_on_missile_hit had a parameter for the shooter. Nice find.

Yeah, there's all sorts of cool **** you can do with triggers. it's always awesome when you find something new.

 

[Antoni]

nice, i need it.

 

[Nikephoros]

Would it be possible to assign these to another kind of weapon, like a crossbow?
And if so, does it need to be applied on the projectile side or on the weapon itself?

 

[Kentucky 『 ＨＥＩＧＵＩ 』 James]

Yes, and projectile.

 

[Nikephoros]

Thanks, i'll try it!

For anyone reading this, if you have a bug where the explosions sometimes doesn't work (doesn't damage enemy). You can duplicate the position to a higher index number, eg (copy_position, pos63, pos1), and use pos63 instead of pos1.

Also, you can use :

(set_fixed_point_multiplier, 100), # to make sure its in centimetres
(try_for_agents,":target", pos63, ":radius"),

That way, it won't iterate literally everyone on the map. Just those within the AOE range.
