Speed of chipmunk decrease

[glurp]

In this maquette https://gist.github.com/1165270

When lines 74/75 are activate, the programe can't work a long time.

In top of file, I do some patch on chipmunk, which are ok for long-time running. but when i append a dynamiques 'rect' and 'rect.remove', the application dead quicly.

Furthermore, I append _app_delete_mouseevent() to Basic.remove :

class Shoes class Basic def remove @app.delete_mouse_events self @app.canvas.remove @real unless @hided @hided = true if self.is_a?(ShapeBase) end end end

I don't kow if it is ok

Hi raubarede,

1st: Within the line 72-76, you've been creating a new rect element each ten times in a second. Even if you remove them, their memory areas are not freed soon. I know this is a problem. But I have not yet found a solution. :(

So, I recommend you to use show/hide instead of create/remove.

2nd: About appending app_delete_mouse_event() to Basic#remove. Looks good. But the Basic#remove method is one of the fundamental methods in Green Shoes, so need to do enough tests.

By the way, when is this patch necessary? What problem does this patch solve?

Could you show me a little snippet to recreate the problem?

Hello ahbb,

My apologise, the code break with delete_mouse_events() Here is the code :

require 'green_shoes'
if ARGV.size>0
    class Shoes
      class Basic
        def remove
          app.delete_mouse_events self
          app.canvas.remove real unless hided
          hided = true if self.is_a?(ShapeBase)
        end
      end
    end
end

Shoes.app width:200,height:200 do
    i=0
    h={}
    n=50
    color=rgb(n,n,n)
    animate(100) do
        h[i].remove if h[i]
        row=i%10 ; col=i/10
        h[i]=oval row*20,col*20,9,{index: i, fill: color}
        h[i].click {  alert( "Hello Teacher:)") }
        i = (i+1)%100
        (n=((n+40)%255);color=rgb(255-n,n,n)) if i==0
    end
end

for the chipmunk maquette, I try to only change colour, it's seem to work. I am not sure that gs+chipnunk will keep on for a long time running... perhaps i must abandon chipmunk.

by, and thank you for the responses

My chipmunk demo is running, I think I understand what's appen : when the number of shape to draw is too high for animate() cadence, then nothing is displayed, we think that application is broken. by limiting the number of shape displayed do ~ max 300 (chipmunk driven+static) the display stay smooth.
