[Moose-dev] Animated grid visualisation

Hi all, as you in this video, I was able to use Roassal to visualize a multi-agent simulation in a grid. https://www.youtube.com/watch?v=EXvsdL5sTRw Now I would like to do animate the simulation without using I/O from user. I try to use the VIVA framework without any success ... Basically, I'm doing one step of the model, modify the elements of the view and do a signalUpdate on the view. |choosenModel aModel nbSteps | choosenModel := ECEC. nbSteps := 200. aModel := choosenModel initialize;new. aModel initSimulation. v := RTView new. b := RTMenuBuilder new view:v. n := (RTMultiLinearColor new) colors: (ColorPalette sequential colors: 9 scheme: 'Greens'). c := n command: [:cells| (cells biomass)/10.0.]. b menu: 'step' background: Color red callback:[ |es| aModel runStep. v removeAllElements. es := (RTBox new color: c; size: 25) elementsOn: aModel theVegetationUnits. v addAll: es. RTGridLayout new gapSize:0; lineItemsCount: aModel spaceModel column; on: v elements. v signalUpdate. ]. v Any hints ? -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/
