I'm pretty sure that this is a SCAR function, but there is no describtion of it in the SCAR manual. Could someone give me the describtion of the parameters and how exactly it works?

Funtion FindDTMRotated(DTM: Integer; var x, y: Integer; x1, y1, x2, y2: Integer; StartAngle, EndAngle, AngleStep: Extended; var Angle: Extended);

DTM - Your DTM.
x, y - Return the place if found.
x1, y1, x2, y2 - Place to search.
StartAngle, EndAngle - How far to rotate in Radians. You can use the function Radians to enter degrees.
AngleStep - Step to rotate each check.
Angle - Returned angle if found.

Example:
FindDTMRotated(Dtm, x, y, MSX1, MSY1, MSX2, MSY2, Radians(-50), Radians(50), 0.05, Angle);

Radians(-50) = 50 degrees left
Radians(50) = 50 degrees right
Higher 0.05 to speed things up, or lower it to slow things down. 0.005 is more accurate but slower.

Thank you very much nielsie :).

I just have one question regarding the function. In your example, will it start searching for it at -50 degrees or at 0 degrees and then go out?

I also have a question regarding runescape… What is the maximum angle from north that the mini-map can be tilted after using MakeCompass('N');?

Thanks nielsie, I learned from that.


However, how would I make radians into degrees? I can handle degrees better.

Or, try to explain radians.

Fizzi: I think it'll start searching at -50 degrees. And the RS can be shifted off very much. I don't know the real numbers, but Wizzup? told me it's 40 degrees sometimes.

r0b0t1:

Radians > Degrees = function Degrees
Degrees > Radians = function Radians

Radians are calculated with Pi, I believe.. 2 * Pi = 180 degrees.

Pi = 180 degrees. 2Pi = 360 degrees. But robot, you can just do Radians(30) to return 30 degrees in radians.

Meh, thanks. That helps a whole lot.


Never knew about radians(deg) though.

What could you do with the angle it returned?

Nielsie didn't say what it returns as…. but I'm pretty sure it returns as a boolean like all other finding functions.

It's a boolean, true if found.
It also sets the var Angle to the angle used to find the DTM.

That's what I mean, what can you do with that angle returned?

Not much, I believe. I don't use it..

if (FindDtmRotated(CrossRoadsDTM, Sx, Sy, MMX1, MMY1, MMX2, MMY2, -Pi/2, Pi/2, 0.1, Angle)) then
  Writeln('We found the angle: ' + FloatToStr(Angle));

Lol… :D

Lol, I was thinking it could give you the radial at which you want to radial walk.

I'm pretty sure that angle is broken anyway… It seems to always return as 0.

I think it works for me although I haven't actually tested to see what Angle was returned. A more practical use for the angle would we to check whether the angle returned is within a certain range. eg:

if (FindDtmRotated(CrossRoadsDTM, Sx, Sy, MMX1, MMY1, MMX2, MMY2, -Pi/2, Pi/2, 0.1, Angle)) then
  if (Angle < 2) and (Angle > -2) then
  begin
    Mouse(Sx, Sy, 1, 1, true);
    etc...
  end; 

But then again you could just make the start and end angles -2 and 2….
