Alright quick poll: Favourite game engine for 3D? I'm super torn between Unreal Engine and Unity. I'm not a super big fan of either engine's approach to entities (inheritance in UE and pseudo-ECS in Unity) but I've just come to terms that developing a new "engine" from scratch for my game is infeasible :( so now I need help deciding haha. Open for other suggestions too ofc

I'm pretty biased toward Unity. Been using it for years and I love its flexibility. There are alternatives to the "pseudo-ECS" if you prefer a strict ECS. Or if you prefer a different style, we can chat about potential workarounds.

@Charanor They're both good, and both have drawbacks.

Unity is faster to slam together a prototype

so i'm using unity and nativearray [now i changed to nativelist, instantiating only once at OnEnable with high capacity, using clear and add instead of dispose [dispose only at ondestroy when game closes] with no success] plus jobs [raycast and boxcast] and unity like creates 12000 GC Alloc calls in profiler

what could i be doing wrong?

i do a lot of raycasts/boxcasts, like 9000 tests in background, each time i call the function manually, for testing, but it's really fast. the only problem is the gc alloc causes a little stutter. but i thought using the nativelist would solve the problem as the doc says the array is unchanged when i call clear and add [only if the capacity is smaller than the new lenght, but i used the constructor with a really high capacity value]

"If the list has reached its current capacity, it copies the original, internal array to a new, larger array, and then deallocates the original."

Almo

what are you putting in the array?

first i do this:
[NonSerialized]NativeList<RaycastCommand>commands1;
void onenable(){
commands1=new NativeList<RaycastCommand>(9216,Allocator.Persistent);
}

Almo

so RaycastCommands

these all have to be allocated

then in the function, I do this:
Vector3 direction1=Vector3.down;
commands1.Clear();results.Clear();for(_i=0;_i<Nodes.Length;_i++){
Vector3 origin1=Nodes[_i].PositionAtGrid;
origin1.y+=(NodeHalfSize.y-.05f);
commands1.Add(new RaycastCommand(origin1,direction1,NodeSize.y));results.Add(new RaycastHit());
}

@Almo oohh

Almo

don't ping me if I'm right here

the noise is annoying :)

sorry, i thougt the button was for linking the next message

i'm planning to

Almo

not a big deal

Arthur 'Gibraltar' Condino

put it all in a coroutine and call yield return every now and then inside the for loop

do you think it'd help
