        if (self.particles) |p| {
            p.deinit(allocator);
            self.particles = null;
        }

// OR

        if (self.particles) |*p| {
            p.deinit(allocator);
            p.* = null;
        }

ping me please, thx!

depends what self.particles and .deinit is

#

if its an ?ArrayList or similar, value copy might not work

#

capturing without a pointer makes a const copy, but usually deinit functions require mutable pointers

@odd dune preety sure the second one would not compile youd still have to do self.particles = null instead of p = null, and what Matthis said ^

2nd one would work with p.* = null

#

need dereference operator to write

#

yeah i meant that, my bad

alright, using the 2nd one 👍
