Code:
if (actor.Pos.X >= self.Pos.X - 24) and (actor.Pos.X <= self.Pos.X + 24) and (actor.Pos.Y >= self.Pos.Y - 25) and (actor.Pos.Y <= self.Pos.Y + 25) and (actor.PinStrength <= 0) then


So basically this thing describes an area or a zone that's square-shaped, that's what I understood, but the problem is that I suck at offsets.
So I thought maybe some of you guys could help me out here, I got a 288x192 sprite, and I want the red area to be the zone/area.

I really suck at this stuff.

General rule of thumb:

Replace the X values(the first two) with half the width.
Replace the Y values(the last two) with half the length.
Much easyer than offsets.

Code:
if (actor.Pos.X >= self.Pos.X - 144) and (actor.Pos.X <= self.Pos.X + 144) and (actor.Pos.Y >= self.Pos.Y - 96) and (actor.Pos.Y <= self.Pos.Y + 96) and (actor.PinStrength <= 0) then

But then it's the whole Module, then it's not just the red zone.

Oh.

My mistake.

Code:
if (actor.Pos.X >= self.Pos.X - 81) and (actor.Pos.X <= self.Pos.X + 81) and (actor.Pos.Y >= self.Pos.Y - 11) and (actor.Pos.Y <= self.Pos.Y + 11) and (actor.PinStrength <= 0) then


Just copy out the area in paint, change the px dim to 1,1 , paste and measure the new px dim.

You lost me at px dim?

If Lua offsets are like every other programming language's offsets ever, you should define everything as if it's the fourth quadrant of a graph.

EG, the top right corner would be X+24, Y+0; then X+whatever, Y+0; etc

Not 100% sure, but that's how, say, C++ would do it, and how Area areas do it.

Uhh. Okay?

Another question,
Code:
for actor in MovableMan.Actors do


Is there any way to make it focus on green team only, and ignore team red?

Go to attributes in paint.

Oh, and my calculations assume that the red area is an object centered around a point.

if actor.Team == 1 then

Add that after the for loop but before anything else.

I'm getting this

Property name was not followed by a value in xxx.rte/xxx.lua at line 1!
Code:
function Update(self)
   for actor in MovableMan.Actors do
   if actor.Team == 1 then
       if (actor.Pos.X >= self.Pos.X - 80) and (actor.Pos.X <= self.Pos.X + 80) and (actor.Pos.Y >= self.Pos.Y - 10) and (actor.Pos.Y <= self.Pos.Y + 10) and (actor.PinStrength <= 0) then
      actor.Health = 0;
       end
   end
end

How in god's name are you getting an .ini error in a .lua file?

How are you loading it?

Are you using IncludeFile = whatever.lua?

Uhmmm... no... :grin:
What do you do instead of IncludeFile?
Author:  Grif [ Sun May 17, 2009 9:45 am ]
Post subject:  Re: "Conveyor zone"
ScriptPath = modulename.rte/script.lua

In whatever object has the script attached.

Post subject:  Re: "Conveyor zone"
So you don't need to include it in the index file? Thanks!

You should also add the corresponding "end" for "if actor.Team == 1 then" ;)
