Asteroids style control
by Joshua "RegularX" Birk · in Torque Game Builder · 04/26/2005 (6:03 am) · 6 replies
I think I'm missing an example here on how to make a player move like asteroids or the old Atari game "Combat" as opposed to a horizontal/vertical shooter (in fact, isn't there a Combat clone laying around here?)
It seems like there's a method I'm flaking on. Does something like .setImpulseForce() merely add velocity in the direction the player is "facing" ?
And as for shooting, I poked at it last night, but might this basic method?
- Mount point to "tip" of player sprite
- On "fire", set rotation to be equal to that of the player sprite
- set velocity in the same way that the player's "forward" function would work.

Gosh darnit, if I had just paid better attention to Melv's force code, I think that would have been evident :)Thanks for the speedy answer Chris.

This was my first pass at the code, and although I've tidied up my code recently, this version is a bit messy and not that great. Still, it was my first project in T2D, and to be honest, the first real game that I'd made.

Feel free to poke through my Biplane Battle code as well for anything you may find useful:www.philspcmods.com/T2D/biplanebattle-beta1-source.zip

I actually did an asteroids clone for my initial test of T2D.Link removed due to bandwidth troubles. If you would like the file, then please inform me and I will email you a link to it

Bizarre internet problems are making it hard for me to glance at code (and posting) :| But I did get it mostly working last night. One quick question - how are you guys capping the velocity of a player? I tried "reseting" the Impulse to getRotation,0 before increasing it agian, but that didn't seem to work. And I tried setting both Linear velocities to zero, but that just stops it dead.

If that's what you are asking, then the solution is rather simple:

Capping as in limiting the speed?If that's what you are asking, then the solution is rather simple:
$player.setMaxLinearVelocity( 20 ); // Change the 20 until desired results

You'll want to look at %obj.setImpulseForcePolar( %angle, %force) - that should do what you want for both your player and bullet movement. And yeah, your basic method for shooting should do the trick :)
