Physics help
« on: March 12, 2010, 08:49:16 pm »
I am wanting to make a program that will simulate physics, but the ones I found I could not understand the source code.  Can anyone help me.  I want to make something like the sonic physics program in the axe section, so that it has friction and jumping/gravity.

I think this is the program you're referring to, right?

Builderboy, I'm also curious.  Could you explain what each little section does so it makes sense?
Builderboy is also the programmer of Peggle, another awesome physics game.  It's in Basic, but I'd still recommend looking at it. :)

Builderboy, you're really good at programs like this. :) Do you mind sharing your methods? ;D

I was specifically saying this program http://ourl.ca/4161/76877 but those programs are good examples too, builderboy could you please tell your secrets?

I'm just going to take a guess and what part of the engine's could be (I have no idea and could be very wrong :P). But it could be something like testing the number of pixels that it is touching/going through/etc. and then just simply applying that to a physics equation (like applying something that calculates gravity). Just a guess :)

Oh, that's right.  I forgot about that one.  Sorry. :)

Btw this one runs much faster on calc than it does in the screenshot. I get like 30 frames per second at least.

It's quite buggy, though :(

* Builderboy begins work on a physics tutorial *

Since that seems to be my strong suit, writing engines :)
