I am pretty sure he wasn't talking to you...

Could that work?

That would be for moving the player, not changing the velocity/angle in a space-like way.

Well, anyway, could you help me out here with the equations for changing the velocity/speed and the angle you are traveling in? I really have no clue what I should do...

Hmm...heres a script a long while ago.

It needs a TON of optimization, at least in ship movement, but I think it should be useful to you...

Especially the coolness nebula effects...

Okiedokie.

Maintain an (dx,dy) for your current velocity. Add to it when you use the thruster in a given direction (dx+accel*cos(ang),dy+accel*sin(ang)) and limit the total speed with a unit vector. Ie:

mag=(dx^2+dy^2)^0.5;
if(mag>maxspeed){
dx=maxspeed*dx/mag;
dy=maxspeed*dy/mag;
}

I learned about vectors and unit vectors in school last week

But I like your explanation kai this is very useful.

Isn't there a way I could do this without saving a dx/dy and just saving the angle you're traveling in and the speed?

[Er1c]

Using angles would make everything else much easier, like shooting projectiles, onwall stuff, upgrades for the ships (like rotation speed upgrades or something), and then I could use the mouse to change the angle for a secondary way to move.

BUT, if it's too hard I'll just use the two velocity variables...

[Er1c]

If I use a vector I wouldn't need the angle... I'll just use the vectors, heh.

Thanks for you're help, Kaimetsu
