Physics Sandbox
« on: October 16, 2010, 05:20:44 am »
Alright i have finally finished my sandbox to where it is workable and very very fun to play with :D It has a handy dandy interface that takes up a crapload of space, but is very shiny and fun :) The screenshot runs a bit fast unfortunately, especially the simulation parts, but i cant seem to fix that.  Here are the controls for the sandbox:

Arrow Keys: Move cursor
2nd: Press and Hold in empty space to create a box
       Press on a box to highlight it
Alpha: Press and Drag to highlight an area
Mode: Start Physics Simulation
Del: Delete Selected Boxes
Clear: Exit

And then there are menu functions.  There are 2 menu's, main and selected.  The selected menu only appears when you have one or more object selected.  The menu is activated by pressing one of the F1-F5 keys, and then the menu selection is chosen using the F1-F5 keys

Main Menu:
All: Highlights all objects
Clr: Erases all objects
Glob: Set global forces in the world
Save: Save the current state of the world
Load: Load the most recent saved state

Highlight Menu:
Copy: Create a copy of the current selection onto the cursor.  Press and hold the copy button to get a preview shadow of your copy selection and move your cursor to place.
Push: Press and hold to create a force onto all selected objects.  Release Push button to apply force and enter simulation
Move: Press and hold to move current objects
Game: You lost it
Edit: Edit the Mass objects as a group (1-24) and set whether or not the highlighted objects are static or not

Awesome. I'll try downloading this now... But maybe TI-Connect won't let me send this to my calc. It's been screwing around with me a lot.

Thanks guys :) I've been working hard on this for the past couple days ^^

Also note that there is a bug that limits your objects to under 24, so don't go over that unless you want a RAM clear.  In the bug fixed version you will be able to go up to 47

Extremely cool and fun to play with, one feature for this that i would like to see added is a 'snap to grid', either for the cursor itself or for the created objects (I think the first one is far easier). Aside from that this is pure awesomeness!

Hmmm snap to objects i can see, but what would snap to cursor do? And yeah, snap to objects would be really complicated x.x i might just do snap to boundaries, but that might get annoying, i usually turn snap off in all the applications i have.

Not 'snap to cursor' but let the cursor move a fixed amount of pixels, so every time I press right the cursor moves 4pxls to the right. Now it is very hard to make two identical boxes without copying because the cursor is very sensitive...
Just like the cursor in SAD, or like any cursor in basic just make the cursor capable of moving by a fixed constant every keypress. Also it seems you can only have one static object? Or did i do something wrong cuz whenever I selected a bunch of boxes and make em static only the first one I selected becomes truly static in the simulation...

Nice!  Very fast, too.  The Source Engine is a lot slower because of the complexity of map collisions.  This one checks with the edges of the screen - a rectangle.  The Source Engine has to check the sides of an object that could be any shape :P

Download!

I really wish I didn't have several papers to write so I could play around with this.

user defined cursor jump distances should be easy to implement and very useful.

this is genius, and you are genius, and after studying the source(assuming you give it) i (hopefully) will be genius as well. it just needs Phun's gearify option and all will be well with the world :P.
thanks, builder! you're the best!

Sounds like a good idea :D What i'm going to do is have a "snap" key (probably XTON or something) that will change the cursor look and change it into snap mode.

Also it seems you can only have one static object? Or did i do something wrong cuz whenever I selected a bunch of boxes and make em static only the first one I selected becomes truly static in the simulation...

Hmmmm i just tried it an it worked fine?

Thanks! :D Speed was definetaly my main goal in Zedd, and according to my calculations, map detection should hardly slow it down at all ^^ Btw did you ever get the Half Life engine demo reuploaded?

thanks, builder! you're the best!

Thanks :] And i most definitely will be giving the source once Zedd and the Sandbox are finished :) Whats the point of a library if i dont give the source ^^ Its for everybody to use and learn from :D

Wow impressive all around. Nice work builder!

Thanks :) Im glad everybody is liking it!
