I want to extract the contents of each field in BrickColors and place the contents into an array, doing so gives me the error
#Accessing fields in struct
gusty kestrel
fields need the instance as the first argument to @field, not the type which only works for decls
random hemlock
so ray.Color?
gusty kestrel
that's also a type
random hemlock
so i assume the brick_color which is the in argument
gusty kestrel
that looks good
you also probably need to do var colors: [fields.len]ray.Color = undefined;
abstract ridge
This is illegal behavior btw
colors[i] accesses colors.ptr which is undefined
random hemlock
hmmmm
prisma delta
remove the inline
gusty kestrel
no you definitely need inline, see my last message
random hemlock
remove the `inline`
prisma delta
nvm im blind 😄
random hemlock
np
prisma delta
i didnt see you make the colors comptime
gusty kestrel
You need inline because fields is comptime-only, but you need (non-comptime) var because brick_color is runtime
abstract ridge
Wouldn't you want
var colors: [brick_color_count]ray.Color = undefined
well the latest is
src/main.zig:79:15: error: cannot store runtime value in compile time variable
colors[i] = @field(brick_color, field.name);?
with
const fields = @typeInfo(BrickColors).Struct.fields;
const brick_color_count = fields.len;
comptime var colors: [brick_color_count]ray.Color = undefined;
inline for (fields, 0..) |field, i| {
colors[i] = @field(brick_color, field.name);
}
oh it compiled haha
but it crashed pretty much instantly
prisma delta
you need an allocator and do:
var colors = allocator.alloc(ray.Color, brick_color_count)
oh yeah 🤣
abstract ridge
If you're returning colors you would need to allocate it though
Unless you want to return it by value
random hemlock
Wouldn't you want
```
var colors: [brick_color_count]ray.Color = undefined
```
with this it does work to access colors at indexes
so it might be another issue that's unrelated to this
so thankks for the help, i'm closer now
it works!
just need some more colors so the effort was worth it
