[Trigger] Hight/Slope

[Supermj]

Ok, for a trigger I'm making, I need one of these two things:

1) A way to detect how much slope is at a point

-or-

2) A way to detect how much higher one point is than another.


Are either of these functions possible?

Try GetLocationZ(location) ?

 

[Supermj]

Does that function say how much higher one point is than an other? I really need to learn JASS...

 

[Eleandor]

No, it gets the height of a certain point. Then do the same for your second point and compare the difference...

Something like this:

• Blabla
  • Custom script: set udg_RealVar1 = GetLocationZ(udg_point1)
  • Custom script: set udg_RealVar2 = GetLocationZ(udg_point2)
  • Set RealVar3 = RealVar1 - RealVar2
  • if RealVar3 > 100 or < -100 then do stuff

Note that if the height of point 2 is greater than point 1, RealVar3 will be negative, so you'll need to check whether the result is > 100 OR < -100

Ok... lets see... I'll test this, and see what you think. (I'll edit this, and PM you)

Oh, I was surprised so you are LGM in the helper xD
Try to ask Cohadar in TH, he made somekind of jump from other slopes thing. He might know something about it.

 

[Supermj]

Shocking... I hardly make any connections to that site, that is my main site for help for triggers... and yes, i am in face LGM there... lol.

 

[FhelZone]

Well, I'll try to ask Cohadar, no I'm afraid he is always busy xD

To get the slope of a point, you'd need something called a terrain normal (it's a vector). Anitarf made a function to get the terrain normal at a point, in his Vector Functions : http://wc3campaigns.net/showthread.php?t=87027

 

[FhelZone]

Wow, to the rescue xD Thanks, I did not need to bother asking him xD

 

[Supermj]

HINDYhat, do you realize what you've given me? A non-vJASSed map of exactically what I've been looking for for about 2 months, and even started to make myself! You've just saved me about 2 days of figuring things out! Thanks!!!

 

[HINDYhat]

Well this is a more complete system that can do the particle physics for you : http://hilton.vs.oiccam.com/showthread.php?t=87031

Vector Functions is just a bunch of functions to help you do vector calculations, like finding a terrain normal and stuff. iNfraNe's particle system uses the Vector Functions to make a neat non-vJass'd physics system. Might be useful for you.

Man... if that's non-vJASS too, I will praise you.
