# 1.00.07 (49537) Mar 5, 2011 Centered each mode in the center of momentum frame # 1.00.06 (49535) Mar 5, 2011 Made earth the same size in sun/earth/moon mode as it is in sun/earth mode Fixed: force vectors are too large in "intro" in sun/earth/moon mode # 1.00.05 (49529) Mar 4, 2011 Fixed: the "to scale" tab should start in earth/satellite mode # 1.00.04 (49527) Mar 4, 2011 # 1.00.03 (49525) Mar 4, 2011 Fixed: Path can still be used to draw Removed confirmation dialog for reset all button Only show arrow indicators when body is too small Improved intro mode parameters # 1.00.02 (49477) Mar 4, 2011 Changed cartoon sun to match up parameters with real sun Renamed "Earth Values" to "Restart" Removed measuring tape from intro tab Removed cartoon scaling Removed scaling control panel Moved measuring tape from "scaling" panel to "show" panel Started a new module # 1.00.01 (49396) Mar 2, 2011 Don't add to the path if the user is dragging the body, see #2767 Reversed the initial velocity of the moon so it will orbit counterclockwise, resolves #2766 Removed unnecessary calls to setBackground Switched to use ControlPanelNode # 1.00.00 (48733) Feb 7, 2011 Initial deploy of 1.00 Added screenshot Renamed from "invert colors" to "white background" Added string for module name # 0.0.25 (48611) Feb 3, 2011 # 0.0.24 (48598) Feb 3, 2011 Improved zoom buttons Zoom buttons become disabled when at max of range # 0.0.23 (48572) Feb 2, 2011 Fixed: zoom was broken for last 2 modes # 0.0.22 (48566) Feb 2, 2011 Made zoom controls smaller Made the grid zoom in and out Fixed the text on the zoom out button # 0.0.21 (48561) Feb 2, 2011 Added zoom controls # 0.0.20 (48357) Jan 31, 2011 Added "Options" menu with "Invert Colors" button, which inverts the colors in the play area but not the control panel # 0.0.19 (48326) Jan 28, 2011 Made "Earth System" button always enabled # 0.0.18 (48312) Jan 27, 2011 Tuned cartoon scaling to prevent more awkward nonlinear motion Perform collisions only in real scale, i.e. only if the physical bodies collide, not if the cartoons collide. # 0.0.17 (48239) Jan 25, 2011 Added a reset button underneath the simulation time readout Made time speed slider work across modes Start time speed slider at 25% instead of 50% Lock in alpha values for cartoon mapping when gravity is disabled, this preserves linear motion # 0.0.16 (48116) Jan 19, 2011 Fixed: stored 'rewind' values get reset during step and rewind # 0.0.15 (48082) Jan 18, 2011 Update force vectors when gravity gets toggled on and off, otherwise displayed value won't update If any of the rewind properties changes while the clock is paused, set a rewind point for all of them simsharing: Save and restore window size simsharing: Don't run physics on teacher machine, fixes stuttering simsharing: Restore bodies after collision Reset grid visibility on reset all Reset measuring tape on reset all simsharing: Save and restore measuring tape visibility and location simsharing: Save and restore scale property simsharing: Save and restore "show grid" property simsharing: Save and restore selected mode Modified the cartoon offset scales for Earth/Satellite mode so that inter-body distance remains the same in cartoon as in real scales # 0.0.14 (47788) Jan 8, 2011 Fixed: dragging an object through a collision still leaves a path drawn, solved by stopping the path after collision Fixed: "return body" after a collision causes a jump in the path drawn, solved by clearing the path after "return body" # 0.0.13 (47777) Jan 7, 2011 Added a grid Added a "return object" button that allows the user to bring back a destroyed or lost object Improved drag handling by converting to a 1-D bisection root finding algorithm for inverting cartoon mapping Made checkbox-gray out a windows specific fix Moved "on" and "off" strings from phetcommon game mode to gravity and orbits Fixed: If you change the values of a system like the mass, or position and then press "Earth values", some force vectors are missing. Removed application specific overrides for adding antialiasing Added horizontal space between gravity control label and on/off buttons change Gravity control to a pair of on/off buttons # 0.0.12 (47614) Jan 4, 2011 Added a continuous interpolation between cartoon and real coordinates and numerical inversion of interpolation # 0.0.11 (47576) Jan 3, 2011 Fixed: mass sliders don't snap to ticks properly Fixed: path looks "crinkly" Added strings for mode names, may be added into tooltips or labels Fixed: Inconsistent icons sizes on mass sliders Fixed: use the same cartoon scales for earth and moon so their radii are proportionately correct Made it so the tape measure icon appears gray instead of white when disabled rescaled control panel to fit on the stage renamed "earth system" to "earth values" fix: append command line args to standard main frame title, instead of replacing title (for sim-sharing) # 0.0.10 (47428) Dec 27, 2010 12/27/10 dev version with many fixes and changes only update camera after switching to new mode, to avoid rendering artifacts ("flash" of large body in some cases) simplify camera, remove animated zoom stuff rewind to proper clock time (last time clock was paused) when Rewind button is pressed rename RestoreProperty to ClockRewindProperty, replace restore with rewind thruout change control panel button color for ADA compliance, and because blue-on-black is hard to see for everyone reduce scale of control panel so that everything fits on stage add "Physics" titled panel around Gravity check box wire up gravity on/off to model MessageFormat i18n (value units) for measuring tape i18n for a couple more strings add Gravity property and check box, not properly wired up to model fixed look of disabled rewind button, required ugly copy of FloatingClockControlNode.StepButtonNode.getDisabledImageRescaleOpScale remove "Large" and "Very Large" min/max labels on mass sliders, so that we don't have i18n issues, and can use "Space Station" label improve tick marks on mass sliders so that you can see where the special value (eg "Our Moon") is reduce font size and unbold the tick mark labels on mass sliders, so that labels don't run together (eg "Large Our Moon") completed i18n, including use of singular/plural for units i18n of mass readouts, to handle ordering of value and units deleted PublicProperty, it's appropriate to move getInitialValue into superclass Change some class name prefixes from "GO" to "GAO" Change some class name prefixes from "GravityAndOrbits" to "GAO", where these classes names will be inlined frequently (eg, GAOStrings) Fixed: replace incomplete "Reset All" node with ResetAllButtonNode Fixed: Sim doesn't pause on reset all Fixed: measuring tape checkbox doesn't reset on 'reset all' Switched back to cartoon image of sun instead of realistic photo # 0.0.09 (47246) Dec 16, 2010 Fixed: Rewind should clear traces Fixed: Rewind button not always enabled when it should be Added rewind button Fixed: Forces don't update when bodies change while paused Added collisions Added real sun image # 0.0.08 (47194) Dec 15, 2010 Switched to satellite image for earth for testing # 0.0.07 (47192) Dec 15, 2010 Fixed: Control panel doesn't fit in the stage Converted overrides to constructor args in modes Added measuring tape to all modes when in real scale Fixed: Earth System button should be disabled when the user hasn't changed any conditions Fixed: earth and moon mass slider icons buggy when in earth moon mode Snap to labeled tick values in mass sliders Added custom tick labels for each body mass slider Added initial support for collisions Made path node fade out Reduced number of integration subdivisions from 1000 to 100 Fixed: Moon mass readout intersects earth mass readout in Sun/Earth/Moon mode Made the space mode express mass in terms of space stations. Fixed slider mass label to read "planet" instead of Earth Fixed mass readout to be in Earth masses instead of "planet" masses Fixed: made the moon magenta when not exactly at moon mass Fixed: the planet is drawn with an earth image when its mass is equal to earth mass, otherwise drawn as a sphere with a gradient paint Fixed scales so velocities are visible in all modes and for real/cartoon scale Added body-specific cartoon scale factors for forces so that all forces are visible in cartoon mode Fixed: Gravity forces don’t appear until you press start. Fixed: play/pause controls should be global instead of independently settable per each mode Changed "Cartoon" to "Cartoon (not to scale)" Fixed: reset all resets the scale mode Fixed: sim doesn't pause on reset Made path lengths depend on the mode, and only go for 1.5 periods of the default orbit Removed moon slider because it takes up too much space Improved mode radio buttons: icons change size with relative body size Improved mode radio buttons: icons are aligned horizontally Converted mode radio button text to icons Fixed: Earth System button should set the mass, velocity, and positions for the bodies to the earth system values within the same mode. Fixed: Drag handlers broken for dragging in cartoon scale Fixed: Moon position doesn't update when switching to real scale Fixed: PathNode should be able to toggle between cartoon/real without disappearing Fixed: label pointer for moon should point the other way in real scale Fixed: velocity vector arrows do not update properly Fixed: velocity vector arrows do not respect scale Fixed icon sizes in the control panel Fixed: Path node is incorrect in cartoon scale Improved cartoon mode Fixed: initial zoom is incorrect Removed animation and zooming Added UI for Earth System button Switched to 4 modes: SP, SPM, PM, Ps Fixed: Location of "x planet mass" seems inconsistent, sometimes above and sometimes below. Fixed: Hard to see where "20 planet masses" text overlaps sun body. # 0.0.05 (46883) Dec 6, 2010 Fixed: "Planet mass" PText is intercepting mouse events. Fixed: My Planet & Space Station slider icon needs to be bigger Added a new mode for My Sun, Planet & Earth Fixed lunar orbit in Sun, Earth & Moon mode Created space station modes # 0.0.04 (46625) Nov 29, 2010 Fixed: Sim should start paused, so that the user has to hit play for motion to start Fixed: Path should only start after user presses "path", not from beginning of simulation Moved the "Moon" checkbox next to "My Sun & Planet" mode radio button, since that is the only mode in which it can be used Made mode radio buttons appear in the same place for all canvases Fixed: Reset all is broken Made trace disappear after 2 earth years Removed the phet logo to save vertical space on the control panel Fixed: In real modes, velocities should not be draggable Fixed: In real modes, bodies should not be draggable Fixed: forces not visible in Sun, Earth, Moon mode Switched to "one canvas per mode" paradigm Made velocity circles more like "my solar system" -added a 'v' to the circle -made the circle gray -made the vectors go behind planets -made the 'v' circle go behind vectors Added arrow icons next to arrow checkboxes Improved performance of path graphics Switched to colors in PhetColorScheme Added a titled border around "show" panel in control panel Renamed and ordered "show" buttons in control panel Removed "to scale" button Initial support for different modes Fixed: force vectors do not update while the sim is paused # 0.0.03 (45917) Nov 10, 2010 Added feasibility test for simsharing # 0.0.02 (45729) Nov 4, 2010 Many improvements for the second version # 0.0.01 (45696) Nov 3, 2010
