Modifying DunDef Code in UT3

[KieranM17]

Hello,

I am currently having a problem modifying the staff from Dungeon Defense in UT3. I'm trying to make it so that the gun fires different projectiles depending on if it is charged or not. I currently have a system that nearly works. At the moment, I can rapid click to fire LinkPlasma or Hold-Click for 1.5seconds (or longer) then release for ShockBall. However, if I don't fire anything for 1.5 seconds, it also fires a ShockBall instead of LinkPlasma.

The part of the code where I think the problem is is here:

event Tick(float DeltaTime)
{
super.Tick(DeltaTime);

if(PendingFire(0) && `TimeSince(LastReleasedTime) > FireInterval[0])
SendToFiringState(0);
}

Currently, I've had to // out the "if(PendingFire(0) && `TimeSince(LastReleasedTime) > FireInterval[0])" as I get and error that says:


Warning/Error Summary
---------------------
c:\program files (x86)\steam\steamapps\common\unreal tournament 3\UTGame\Src\MPHMutator\MPHWeap_BasicGun.uc(54) : Error, Unknown macro 'TimeSince'.

Failure - 1 error(s), 0 warning(s)

Execution of commandlet took: 1.76 seconds

Any Help?

Thanks,
Kieran

PS. Here is the full code for the weapon, Please ignore the sloppyness. Once I get the gun functioning, then I'll do some tidying!:

In UT3? The source code is meant for UDK, not UT3.

In UT3? The source code is meant for UDK, not UT3.

Indeed it is, but I've got everything working apart from this one bit. I'm wondering where the "TimeSince" macro comes from. Does it come from UDK or can be found in DunDef Source?

[Graylord]

I can't find any such macro in UDK myself, so it might be in the DunDef codes.

(Though I am relying on a automated search, so it may not be accurate.)

[KieranM17]

I can't find any such macro in UDK myself, so it might be in the DunDef codes.

Ok, any ideas where macros are usually saved? Are they inside .uc files, if so, would they be in a parent class, or can they be gotten from elsewhere? If I know where about to find it, I should be able to implement it. :) I haven't worked with macros in UScript before.

Thanks,
Kieran

DunDef have indeed used their own Macro. They essentially used their own timers based on DeltaTime; it's the time since the button was last released. You can work it out yourself, you don't need to copy and paste the macro.

Ok, Thanks! Now I just need to check UDN on how to actually write macros in UScript! ;)
