Can Objects react like Particles?

[dienben]

Hello,

Yeah, you could do it!

First, you need to build your wall. Eack brick must be a object. You coud do that with a grid and use the grid to clone a single brick, or clone one brick manualy (second method is versy simple: fisrt one cube, then you clone, then you select the 2 cubes and you clone, then you select the four ...).

Don't forget to put your wall on a plane (the ground)

Next, go to the logic panel (the little pink pacman) and select actor / dynamic and rigib body.
Use the bonding box property to define the intercation.

Then add a sphere, put the same parameter (rigid, dynamic etc...) and give it a initial speed and a direction: the wall!

Play the simulation (game engine) [P].

The ball will break the wall. You must play with the different parameter to obtain what you want. When you are satisfied, record the simulation (game ->record game physics to IPO).

Play and modify your animation (Alt A).

You did it!

Cheers

Dienben

Do you want to use the game engine? Do you need this wall being blowed up in a game?

If you want to make just an animation, you don't need the game engine, acctualy you can't use it for an animation.

To make an object being affected by force-fields you must declare it as a softbody
go to the animation window (F7) and find the physics button on the header
here you'll find panels for softbodies, deflection, particles and so on
make one brick, make it a softbody with a high value for "stiff edges"
Shift+D to duplicate the brick

Thanks Stefce, I tried that before your reply but found even with stifness that the soft bodies stuck to each other and became rather rubbery! I have seen game baking tutorialed elsewhere but will try writing to IPO, thanks dienben.
