Algodoo

A rocket that homes in on whatever target you aim it at (as long as the target has 11 controlleracc). If you're going to shoot it at a target, make sure the rocket is pointed toward the ground, or it'll go crazy. There's an airfriction brake on it to slow it down if it goes nuts, but it might not be enough, so be careful.

When you play the scene, the rocket will be moving leftwards at 5 meters per second, so that the laser can hit the target box.

There is a small explosive charge at the tip of the rocket, so when it hits the target, or ground near the target, it'll explode.

One more thing. This rocket is not advanced enough to work well with gravity on. Maybe if you point the rocket down at the target from WAY up high, but otherwise try to keep gravity off.

Oh yeah, and it uses readables, so Algodoo 2.0.0 and higher can use this, but nothing older than that. (I know that some of you out there still use 1.8.5 for some reason, so I thought I'd just warn you about the readables.)

P.S.: Forgot to tell y'all, there's a thruster stabilizer on the rocket, for all of you that like thruster scripting. So if you want to use my rocket scripting and stuff, go right ahead. But if you use the actual body and exact scripts, make sure you give me credit in some way.

UPDATES:

Added a Fruitilizer Wing for HUGELY increased accuracy. Now strikes targets with great ease if they're below the rocket.
Made the stabilizer more powerful, to counter-act the wing's angular movement damping.
Changed the rocket position, the target, the starting rocket velocity, and gravity has been turned on.

Update2:

Added a rocket mortar. Press on the triangular trigger to fire. Breach loaded.
