Help With a Steering Expression.

[Big_Adam]

Good Day.

I come here once agin with a problem many (I hope) will answer with ease.

Anyway, I'm building a Stolly (6x6 boat car truck ... thing) and I want the steering to be done via two thrusters that only work in water.

So I have my truck, 2 thruster with a 5000 multiplier and an adv.pod controller.

I tried this.

N@Stolly_Con
I@Water A S D W Active
O@Wleft Wright Tleft Tright
Active==0 W==0 A==0 S==0 D==0 Water==1-> Tleft=0 Tright=0;
Active==1 W==0 A==0 S==1 D==0 Water==1-> Tleft=-1 Tright=-1;
Active==1 W==1 A==0 S==0 D==0 Water==1-> Tleft=1 Tright=1;

But one thruster (Tright I think) just kept going full pelt all the tie regardless. I also tried the Out=(statment?T:F) way of writing it but I just don't know how to write an expression where multiple key presses do multiple things.

What I would like is for when in water for the following to happen.

W = Both thruster forward.
S = Both thrusters backward.
A = One thruster forward, one backwards.
D = One thruster forward, one backwards but the otherway round to A.

So can anyone help me please?




My Stolly.

Well im not sure what Wleft and Wright are but ill give it a go

N@Stolly_Con
I@Water A S D W Active
O@Wleft Wright Tleft Tright
W==1&Water&Active -> Tleft=1;
W==1&Water&Active -> Tright=1;
S==1&Water&Active -> Tleft=-1;
S==1&Water&Active -> Tright=-1;
A==1&Water&Active -> Tleft=0;
A==1&Water&Active -> Tright=1;
D==1&Water&Active -> Tleft=1;
D==1&Water&Active -> Tright=0;

it probably looks a bit complex, but thats cause i dont know how to make it shorter to be honest :P

N@Stolly_Con
I@Water A S D W Active
O@Wleft Wright Tleft Tright
Active==0 & W==0 & A==0 & S==0 & D==0 & Water==1-> Tleft=0 Tright=0;
Active==1 & W==0 & A==0 & S==1 & D==0 & Water==1-> Tleft=-1 Tright=-1;
Active==1 & W==1 & A==0 & S==0 & D==0 & Water==1-> Tleft=1 Tright=1;

& = and
| = or

untested but should work:

N@Stolly_Con
I@Water A S D W Active
O@Wleft Wright Tleft Tright
Tleft = (Water & Active ? (W | D ? 1 : (S | A ? -1 : 0)) : 0)
Tleft = (Water & Active ? (S | A ? 1 : (W | D ? -1 : 0)) : 0)

Well, maybe the concept of what you would do with wheels could help here. With wheels, the formula could be (adding the water argument to make it a bit more relevant)
Leftwheels = (W - S - A + D)*Water
Rightwheels = (W - S - D + A)*Water

If there are two thrusters in the back, one on the far left side of the back, and one on the right, both in a position to move the vehicle forward if they were to both turn on, then this formula should work for that too. Only problem, is that if it's only those two thrusters making it turn, it might turn a bit awkwardly.

Uhm W-S-A+D is exactly the same as W-S-D+A ?

it's the same as 2+3 = 5 But guess what.. 3 + 2=also 5! I'm a math genious

No, it's not. Say you're pressing just A.
0-0-1+0 = -1
0-0-0+1 = +1
Left tires go backward, right tires go forward, turning to the left.
Mine involves subtraction. 3-2 is not the same is 2-3.

Im gonna ask a dumb question but how do you make vehicle suspension. I would love to lean how
