Not for ghost.zh but there is a video tutorial for setting up autoghost enemies that Saffith put together.

[Imzogelmo]

I pretty much looked at Saffith's examples and read his ghost.txt file to figure out how to do them. The demo video he put on YouTube helped a lot too. I've never even made any scripts more than a couple dozen lines long before, but I wanted to make an enemy to push myself to get a bit better. From there, it was a lot of trial and error to get it working just right. OK, that last part is still ongoing.

How do we use GHF_NO_FALL I've tried using it but it doesn't seem to do anything.

EDIT: I was ANDing instead of ORing it. That was the problem. This is fixed now.

I'm having trouble making multiple enemies on the screen when using ghost.zh. NumNPCs is staying at 1, so AutoGhost() isn't making them, and I don't know why. Any ideas?

[Mero]

Did you add he GhostZHActive script to the active slot, or your own script? If it's you're own could you post it please.

[Imzogelmo]

No, just using the GhostZHActive script that is included in ghost.zh.

Did you set attributes 11 and 12 if either of those = 0 it won't work.
Also could you post this enemy script so I could better help you. Thanks.

[Imzogelmo]

The attributes 11 and 12 are set correctly. The first enemy is a ghosted enemy and is working fine. Any subsequent enemies (ghosted or not) do not appear at all.

The script I'm using is my Spark_SMB2 script, which is in this topic:

Okay I'll read though it, and see if I can figure out what is wrong.

[Imzogelmo]

Oh, please disregard. It wasn't a problem with the script, just with the user.

Umm... Okay then...

Question about enemy bait.

I was looking in Ghost.zh and I noticed something: The enemy bait is only found when it's within 14 pixels of the Y coordinate of the monster. Is that right? There's no equivalent check for the X?

I always wondered what the actual behavior was.

I think there's a bug in the Ghost_CanMove() function. I used a typical empty NES dungeon room with just the walls and this script:

CODE

const int TEST_DISTANCE = 1;

ffc script testenemy {
   void run(int enemyID) {
      npc ghost = Ghost_InitAutoGhost(this, enemyID);

      while(true) {
         Ghost_X = 32 + TEST_DISTANCE;
         Ghost_Y = Ghost_X;
         TraceB(Ghost_CanMove(DIR_UP, TEST_DISTANCE, 0));
         TraceB(Ghost_CanMove(DIR_LEFT, TEST_DISTANCE, 0));
         Ghost_X = 208 - TEST_DISTANCE;
         Ghost_Y = 128 - TEST_DISTANCE;
         TraceB(Ghost_CanMove(DIR_DOWN, TEST_DISTANCE, 0));
         TraceB(Ghost_CanMove(DIR_RIGHT, TEST_DISTANCE, 0));
         Ghost_HP = 0;
         Ghost_Waitframe(this, ghost, true, true);
      }
   }
}

The script printed this in allegro.log:

CODE

true
true
false
false

Shouldn't it print true 4 times? It also doesn't matter what TEST_DISTANCE is set to.

Another bug. Ghost_Explode doesn't incorporate the Draw*Offsets. Can you fix this?

I'll check it out.

Is drift suppose to ignore normal movement?

D'oh.

Another problem with constantwalk4. It seems the enemies position is being snapped to the grid both directions. It should only be snapped to the grid on the axis it's NOT moving.

No, they're supposed to snap both ways.

I was looking in Ghost.zh and I noticed something: The enemy bait is only found when it's within 14 pixels of the Y coordinate of the monster. Is that right? There's no equivalent check for the X?

You misread that. It checks if the Y distance is greater than 14 and moves up or down if so, and left or right if not.

I think there's a bug in the Ghost_CanMove() function. I used a typical empty NES dungeon room with just the walls and this script:

Huh. Yeah, that's not right. I'll look at it.

[Mero]

You're absolutely right about the snapping to the grid. The real problem is how you handle the counter. You need to change it to a float and cap it. Then decrement it by the step / 100. Also the step variable needs to be a variable. This will fix the shift bug. What is the shift bug. set step to the step of a blue darknut to find out.
