Cap MaxZ and MinZ

[MrArgh]

Hi!

I'm trying to do a simple function that will cap my vehicle's Z value (both Max and Min). My plan is simply to check if my vehicle is above a Z-value (2500.0 at the moment) and then either set it back to 2500.0 or set the velocity to 0.

Currently this is my very unfunctional code:

				
function EndGame()
{
	`log(MyPos);
	MyPos = self.Location;
	MaxZHeight = 2500.0;

	if (MyPos.Z > 2500.0)
	{
		//hopp = vect(MyPos.X,MyPos.Y,MaxZHeight);
		MyPos.Z = MaxZHeight;
		self.SetLocation(MyPos);
		

		
	}
}

Could it have to do with the fact that I first declare that MyPos = self.Location and I after that change MyPos.Z?

My other plan was to create a new vector (hopp), however the compiler complains that it is lacking a X, Y or Z-value (float MaxZHeight).
I can't even write: hopp = vect(MyPos.X,MyPos.Y,MyPos.Z) something that confuses me.

Thanks in advance =)

vect() requires constant values as it's a compiler directive not a function that creates a vector.

Using "self" is a waste of time except as a function argument to something that requires an object reference.

function EndGame()
{
    if(Location.Z > MaxZHeight)
    {
        MyPos = Location;
        MyPos.Z = MaxZHeight;
        SetLocation(MyPos);
    }
}

I see - I'll stop using self then =)

Thanks a lot for the help with the code - makes sense.
Another issue I ran into is the fact that this function lies in my vehicle-class though I'm wondering if I have to put it into my Pawn-class (or reference to it in my Vehicle-script)?

[Blade[UG]]

well that depends on if you want to be adjusting the Z location of the Vehicle or of the Pawn ?

[MrArgh]

I got it to work quite alright on my Pawn, however nothing happens when I write it in my vehicle-class.

Could it be that I need to refer to my PlayerController with this code when I'm in the vehicle?

Edit: Alright, I tried to set use Set Location in my Vehicle-class but nothing really happens - except that the vehicle stops in a fixed location (no gravity) though not in the location that I have assigned.

function EndGame()
{
MyPos = vect(0.0,0.0,0.0);
SetLocation(MyPos);
}

I'm sort of curious, what's the actual purpose of doing this, anyway?

Probably need to call SetRBLocation on the Vehicle's Mesh, because it's a physics object, it doesn't follow a lot of the Unreal physics stuff

[MrArgh]

I'm basically trying to create a boat using an extended Manta. Our plan is to include floating/buoyancy and I just want to make sure that the boat never gets higher/lower than a certain value - and this must apply both when driving and not driving the boat.

If I try SetRBLocation, should this be done in my vehicle class or my vehicle content class? (My classes follow the same hierarchy as the regular manta).

[Blade[UG]]

Should be done wherever you have access to the Mesh. So why is the function called "EndGame()" if you're trying to make it regularly stay at a certain level? *confused*

[MrArgh]

The function name is just stupid of me, it has nothing to do with what I want it to do. I just named it that when I started working on the function. When I get it to work I'll rename it =)

Alright, so I'll try and use SetRBLocation on the Vehicle's mesh and see how that turns out. I'll most likely get back if it doesn't work.

And, I don't mean to be an irritating question-asker, but do you have any idea on how to solve this: http://forums.epicgames.com/showthread.php?t=772150

Anyway, thanks for the help!

Alright, my vehicle doesn't go above my desired MaxZValue - working as intended.
One more thing I need to do is to set Velocity to 0 when it reaches this value. Is there something like SetLocation for Velocity?

My code:

function CapHeight()
{
	
	MaxZHeight = 2500.0;
	`log(Velocity);
	
	
    if(Location.Z > MaxZHeight)
    {
    	MyPos = Location;
             MyPos.Z = MaxZHeight;
	Mesh.SetRBPosition(MyPos);
    }
}

I was thinking of AddVelocity but I'm kinda uncertain about the parameters.

[Blade[UG]]

I'd SetPhysics(PHYS_None); that should pretty much ensure it stops

[MrArgh]

Indeed it stops =)
The thing is, after that I need it to fall down again - so I tried setting Physics to RigidBody after Phys_None; the issue is that the vehicle still seem to have input from my jump (because it is pushed up when RigidBody physics is applied...).

Edit: The easiest thing would be if there is a function in which I can set my Pawn/Vehicle's speed to 0 immediately. I tried to change both Velocity and Acceleration but not much happened. Unless I have to apply it to my Pawn(or vehicle mesh?) specifically?

[Blade[UG]]

open up PrimitiveComponent and have a look through the functions there?

[MrArgh]

Thanks Blade - I found the answer there.
I used: Mesh.SetRBLinearVelocity(MyVelocity);

That more or less settles it - my function is done =)
