Tank Simulator

Okay, I'm making a tank simulator. Problem is, I don't know how to get the camera working to see the tank from the back and NOT the front, as you'll see in the code that I whipped up below. Also, how can I make some realistic gravity? Oh, and please don't say anything about the terrain-I know it's a problem.

| Oh and yes, the tadpole is one of the geometrix models included with Blitz3D. |
| ||
| Just position the camera at 0,0,-50 rather than 0,0,50 and you'll see the back. Take you're collision commands out of the main loop too, you only need to call them once after you assign the types. Stevie |

By "back," I meant that I could see the back of the tank, kind of like the games Uru, Gundam Crossfire, and the such where you see the back of the machine. So here's the updated code:

| Sonokong, check out the code archives, theres a few funcitons in there which would qualify for this. check out SUPERCAM for example. IPete2. |
| ||
| Hmmm... supercam is good, but I'm not so sure it's right in this case. Is there a way to shoot pre-made missiles out of the "gun barrel" of the tank? I've got the model and everything, all I need is the code for shooting out of the "gun barrel". I'm not so sure it's all possible. |
| ||
| If the missiles are a child of the tank model (EntityParent missile, tank), in every position, the starting/launching position of the missiles are the same. So, in a separate program, figure out what these coordinates should be (say, with the mouse) and apply them on every launch. |
| ||
| Okay |
| ||
| Oh yeah, the tank keeps on going through the ground at times because of a glitch. |
| ||
| Maybe use TerrainY() to place the vehicle on the ground? Or use a LinePick from the tank to the ground and place it on PickedX(), PickedY(), PickedZ() Else, just tweak the code to avoid this glitch. |
