Trouble using SetActorPosition and GetActorX/Y/Z

[Ravick]

Hi there.

I was trying to mimic the 'walking' monster behavior with acs for any intended actor. I mean, it should 'pretend' the TAG actor was moving toward to the player who activated the script. I thought it'd be just check if actor's position coordinates were bigger or smaller the respective player's coordinates and just increase or decrease them according, repeatedly.

But it works... erradicly. Some actors does only move when player changes its Z coordinate, some actors moves outside the map, some does just move in one or two of the three coordinates, and some actors do not move at all. I have no clue of what I'm doing wrong. If someone could give some light here, it'd be appreciated.

The script follows:

Code: Select all

    
    int QualX;
    int QualY;
    int QUalZ;
    
 Script 6 (int Qual)
 {

// Defines X:
    If (GetActorX (Qual) < GetActorX (0))
        {
            QualX = (GetActorX (Qual) + 1.0);
        }
    Else If (GetActorX (Qual) < GetActorX (0))
        {
            QualX = (GetActorX (Qual) - 1.0);
        }
 
// Defines Y:
    If (GetActorY (Qual) < GetActorY (0))
        {
            QualY = (GetActorY (Qual) + 1.0);
        }
    Else If (GetActorY (Qual) > GetActorY (0))
        {
            QualY = (GetActorY (Qual) - 1.0);
        }

// Defines Z:
    If (GetActorZ (Qual) < GetActorZ (0))
        {
            QualZ = (GetActorZ (Qual) + 1.0);
        }
    Else If (GetActorZ (Qual) > GetActorZ (0))
        {
            QualZ = (GetActorZ (Qual) - 1.0);
        }
 
 //Sets new coords to QUAL actor:
    SetActorPosition (Qual, QualX, QualY, QualZ, 0);
    Delay (1);
    Restart;
 }

Thanks in advanced!

Think there's a typo in the second part of defines x.
Both if and else lines have <. The second one should have >.

Humm... that explains some of the odd behavior. I guess the rest of it is because the script fails to put the actor in XYZ positions where it collides with level geometry. (It is a guess, however.)

Thanks

You're right. Setactorposition doesn't force them to move to the position, only if it's open.

You might want to take a look at Warp. It is more flexible and you can force movement with one of it's flags as well.

You can use it the same way by using the WARPF_ABSOLUTEPOSITION flag (to use coordinates).

It was way better indeed! Thanks!
