  Problems with SetMagnitude... Again.OK, frankly, I'm pretty sure this should work:
Code: function Create(self) self.VelMag = 0; self.VelMag = self.Vel.Magnitude; self.NewV = Vector(0,0); end function Update(self) if self.Vel.Magnitude < 80 then self.NewV = self.Vel; self.NewV:SetMagnitude(self.VelMag); self.Vel = Self.NewV; end end And yet it doesn't. When run, the console just returns "No overload of Vector:SetMagnitude(const.Vector,number) matched the arguments Vector:SetMagnitude(custom[float])". I also tried just typing self.NewV:SetMagnitude(80); , but that doesn't work either. Any thoughts on the reason? |

Re: Problems with SetMagnitude... Again. That's the same as this:
Code: 80 You need a variable. Code: numberofsheep = 80 Like that. |

Re: Problems with SetMagnitude... Again. Eh, no?
I changed the code to Code: function Create(self) self.NewMag = 80; self.NewV = Vector(0,0); end function Update(self) if self.Vel.Magnitude < 80 then self.NewV = self.Vel; self.NewV:SetMagnitude(self.NewMag); self.Vel = Self.NewV; end end And it still doesn't work. |

Re: Problems with SetMagnitude... Again. What CaveCricket48 means is this:
Code: self.NewV:SetMagnitude(self.NewMag); This doesn't actually change the variable; it returns a copy of the variable with the magnitude changed. You want this: Code: self.NewV = self.NewV:SetMagnitude(self.NewMag); |

Re: Problems with SetMagnitude... Again. Gee, you're right!
...Even so, Code: function Create(self) self.NewMag = 80; self.NewV = Vector(0,0); end function Update(self) if self.Vel.Magnitude < 80 then self.NewV = self.Vel; self.NewV = self.NewV:SetMagnitude(self.NewMag); self.Vel = Self.NewV; end end Still doesn't work. Same error as before. |

Re: Problems with SetMagnitude... Again. You capitalized the "S" in the last self. (ie. change Self.NewV to self.NewV)

Re: Problems with SetMagnitude... Again. You're right about that.
What doesn't affect the fact that the error appears on the SetMagnitude function, not on that line. |

Re: Problems with SetMagnitude... Again. Try, instead of
Code: self.NewV = self.Vel do Code: self.NewV = Vector(self.Vel.X,self.Vel.Y)) Do the same with all vector calling/setting. While both should have the same results, I've had instances where that's not the case. |

Re: Problems with SetMagnitude... Again. That just did the trick. Which is kind of creepy, actually.
Many thanks to ye all. |

Re: Problems with SetMagnitude... Again. I'm still curious why using SetMagnitude didn't work out right. Anyone know why?

Re: Problems with SetMagnitude... Again. It's an issue in the actual engine, which is written in C++. The function doesn't take a constant value, but apparently the variables are stored as constant values, while creating a new Vector is a different story.

Re: Problems with SetMagnitude... Again. That's really odd, but that does sort of make sense. Now I'm just wondering when the engine considers a Lua variable a constant and when it doesn't?

Re: Problems with SetMagnitude... Again. Presumably, at completely batshit insane times that are wholly unpredictable.
Remember, this is Cortex Command. |
