Exec Function help

[1Lt Coagulator]

Hello. I am trying to log when an exec function is called, but I don't think I am doing it right. here's the code:

exec function SwitchToBestWeapon (optional bool bForceNewWeapon)
{

		`log("***************************SWITCH HAS BEEN CALLED");

}

very primitive and probably incorrect, but I believe it worked in 2k4. Can someone point me in the right direction?

Where did you add this functions?

[1Lt Coagulator]

Thank you for the reply. I added it at the bottom of a vehicle function, but right above the default properties. What confuses be is that i also tried this with vehicle horn, and it still didn't write to the log. I will have to check the link you gave me to see what im doing wrong. I am testing with Unreal Ed, after compiling.

[RattleSN4K3]

So what class?
There are limitations. You can check the page i posted on my previous post. It's a updated version (UDK compatible) so the valid classes where to put exec functions into might be different.

Classes that are scanned for exec functions are (including all subclasses):

• Input
• Controller
• Pawn
• InventoryManager
• Weapon
• HUD
• GameInfo
• CheatManager
• GameViewportClient
• Interaction - Interactions placed into a PlayerController's Interactions array will be executed, but will not show up in the console command completion

What are you trying to achieve, what do you want to do?

I have this:

I want to make them fly like the UT space fighter. I was able to get some Z axis movement by this

bAllowZThrust=true

but The other issue is that the roll of the craft causes the stay upright parameter to adjust too much, and sometimes spin out.

The Exec Function: When Finished, I would like for it to ask the player if they want to Stop in mid-air, (which I know requires menu elements, I'm going to work on that) and does so, setting the rotation to the upright position.

I saw your post in the Forum about the fury controls regarding the UT space fighter. I tried making a new vehicle class, extending UT vehicle, but I encountered several problems: It doesn't move, and any input I give it has no response. Should this:

New Update: Able to get the redeemer method to work (somewhat). It rolls, but It isn't Moving (no airspeed). I don't know what the problem is, but I am looking at it.

EDIT: ABLE to get the spacefighter Rotation to work, although it is kinda jumpy. I am unable to get it to move, however. The current movement code is at top.

This might be releveant, for both this thread and the other one about the fury.


- Some weeks ago i took the 'Skaarj SpaceFighter' from 'Unreal' and i used the Cicada for the code.

- The cicada is very easy to tweak and change; but i cannot comment on the Fury.
-maybe trying the cicada code will be easier, or maybe it does not have the stuff you want... but i thought i would pitch in anyway

- i had problems with new projectiles though

[1Lt Coagulator]

Thanks for the reply, but This code is from the UT2k4 AsVehicle_Spacefighter.UC (unless you were pointing that to me in the first place ). The issue is that for some reason, I can't link the Pawn's velocity with the forward velocity. I am looking into it, but I really do appreciate it!

[RattleSN4K3]

Do you use the UTVehicle class as base? In that case, you need to implement the rotation code into the VehicleWeapon code.

[1Lt Coagulator]

Big Edit: Able to get craft to move using an addimpulse, but now it doesn't even turn.
In the Autostate, If I had

SetPhysics(PHYSNone)

Then It wouldn't move, but turn.

If it was

SetPhysics(PHYS_Flying)

Then it wouldn't Turn, but fly in the direction the camera is pointing...

Why is this happening?

I also made another vehicle, kept the simobject, and just added impulse without quaternions, and stuff. It actually flew, and turned, and adjusted to where you turn. How Can I keep it from Spinning from trying to remain with the top facing a positive Direction on the Z-Axis? If I can get this to work, It'll help alot.

[1Lt Coagulator]

I am not sure if Anyone knows, But it seems that the SetRotation() function doesn't really work in this case, or this is what is causing the problem. It doesn't work if Physics are set to Phys_Flying under faceRotation(). I'm going to try it under a tick function.


Also, I'm having a Problem with A configureable mutator. I've followed this http://www.moddb.com/games/unreal-to...rable-mutators to the letter, and read all the posts. I tried everything that there was on the page, couldn't find a solution. I'm using mapmixer, but it says it's unable to find the UIScene (even though it's in the background), the menu background ceases panning, and then both UIScenes (yes, the one I created and Mapmixer's mutator list) are visible on the screen. I've spent 5 hours trying to solve it, perhaps I just need sleep, but advice is appreciated. I'll post whether or not I solve it.

Edit: Problem Still Unsolved, Still reviewing for errors, as well as the Phys_Flying issue.

[1Lt Coagulator]

Big Edit: Ut3 3d Flight has been Achieved, although primitive. If anyone is following and would like to know how, let it be known.

[RattleSN4K3]

I'm interested. Please, post it here so anyone can read it.

Where the red text is is the sole problem that Gets the ship to point in the right Direction. What it needs to be replaced with:

SetRBRotation(NewRotation);

The reason or explanation: Through trial and error, I have seen that when the physics is set to PHYS_NONE, it rotates to the desired location, but doesn't move because

Mesh.AddImpulse(Impulse,,,true);

Only effects a body with physics that allows for forces (in this case a velocity, as denoted by TRUE) to effect it. When the physics is set to Phys_Flying for example, It is now able to be pushed, so to speak. However, it does not rotate; changing the

SetRotation(NewRotation) <---Change to ---> SetRBRotation(NewRotation);

should turn it in that direction, although I'm currently trying to remake what I had previously.

I got a hint from this thread: http://forums.epicgames.com/threads/...highlight=spin
Even though this code is from UT2004, I was able to change it and allow (somewhat) usable space flight. I really dont know why it acts the way it does, I really dont understand the quaternions (I even took calculus 3), but I'm going to try and replicate flight from an MMORPG called Ace Online.

My ONLY problem is that with what I have now, It rotates as FAST AS THE USER CAN MOVE THE MOUSE. I don't know how to change this, But I will be looking into it. The flight is primitive, and unstable, but I'll keep in touch.
