Flock of Birds (boids) With Class and operation overloading takes too much mem

(1/1)

Dzandaa:
Hi

This is a demonstration showing a Flock of Birds based on Boids artificial life program created by Craig Reynolds.

Using OpenGL, work on Linux and Windows.

Have fun.

Dzandaa:
Hi again,

I realize that I Didn't manage well operator overloading with a Class (memory eating!!!)

This version is just using records.

Hi
Memory eating... You think  :D
The first version just "bricked" my lappy  >:D

Dzandaa:
Hi,
@cbdc

I'm very sorry for that!!!

I didn't find any example with operator overloading in a class.

Just overloading of Records.

The problem come with vector2u.

If anybody have an example with overloading operators in classes, I'm interested (Form based application)

Example:


--- Code: Pascal  [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---operator + (const V1: Vector2; Val: Single): Vector2;begin//      result.X := V1.X + Val; // <-- Solution one crashes because result is not initialized.//      result.Y := V1.Y + Val; exit(Vector2.Create(V1.X + Val, V1.Y + Val)); // Solution 2 works but didn't free the memoryend;

"Bricked"? Rendered indistinguishable from a boat anchor? Surely not... :-)

@Dzandaa You should have put "boids" in the subject line: I'm sure I'm not the only person around here who'd understand the allusion. I remember when this was first discussed in the late 80s, and always find myself thinking of it when I see something like the Rutan Ares.
