| Post subject: | Getting the height of the terrain |
I was doing a landmine, and realized that it sometimes becomes terrain. To solve it, I set in the .lua file self.ToSettle = false and self.Age = 0, and still, sometimes it still turns into terrain. To prevent this, I thought that if I could make it float like 2 or 3 pixels above the terrain, it wouldn't become it. First, would that help? And second, how could I get the height it has from the ground and make the gib float over it? |

Lizard found that if set something to MissionCritical = 1, you keep it from becoming terrain. For your mine, set it to MissionCritical = 1 in function Update(), but turn it to MissionCritical = 0 right before detonating it. Pinning something, combined with "ToSettle = false" also keeps it from turning to terrain. |

Nice. So, in the update self I set self.MissionCritical = 1, and in the detonation if I set self.MissionCritical = 0 and then Self.GibThis(), right? |

Yes. |

Now that was quick. Wait, if I set in the lua, the booleans are true/false or 1/0? |

Just wondering, what else can this be applied to? |

The MissionCritical flag? Most likely, it's set up as a general property for all MOs, meaning that any actor, item, particle, or, really, anything that isn't terrain could use it. The only dubious one in that list is, maybe, mopixels, but they're often included in general MO properties. |

Wait, now I want to get the height of the terrain for another thing. How can I get it? |

Self.Altitude is what you want. |

Altitude works with the height of the terrain? I mean, if I have a hill, and I want an object to get pinned when it's 5 pixels above ground, it would work in any part of the scene? |

That's what it's for. |

self.Altitude doesn't seem to work. I used a code that went like this: Code: function Update(self) if self.Altitude <= 5 then self.PinStrength = 9999; end end And the lua console says "attempt to compare nil with a number". |

Ah, I've given you the wrong syntax. Try self:GetAltitude(0,7) |
