 Need the help of the lua gods! I need a script that will hold a drop-ship a certain amount of pixels above the terrain. So if the terrain goes up, the craft goes up and the other way around. Maybe if it holds each engine above the terrain individually so if there's an incline the first side to hit it goes up, then the other side.
I'm not too sure if this is clear enough so if more information is needed ask me. Also, I very much appreciate any help that is given.

Re: Need the help of the lua gods! I'm not entirely sure what it is that you want.
From that, I understood to make it so that crafts are impossible to touch the ground?

Re: Need the help of the lua gods! Yeah, just to stay at a certain level right above the ground, like hovering just a few pixels above the ground.

Re: Need the help of the lua gods! You need to cast a ray to the closest piece of terrain, and make sure your Y position is however much above that.

Re: Need the help of the lua gods! What would a script like that look like? I can't code in lua.

Re: Need the help of the lua gods! Actually there's a better way to do that, MORays are a little more complicated than: Code: function Create(self)
self.MaxHover = 15; --The maximum height above terrain the object will fly.
self.MinHover = 10; --The minimum height it will fly.
end
function Update(self)
self.Altitude = SceneMan:FindAltitude(self.Pos, 0, 2);
if self.Altitude <= self.MaxHover then
if self.Vel.Y = self.Vel.Y + 1;
elseif self.Altitude >= self.MinHover then
self.Vel.Y = self.Vel.Y -1;
end
end Pretty sure that should be bug free.

Re: Need the help of the lua gods! Thanks for the code Roast! Code: ERROR: Drop Ship Template.rte/hover.lua:9: 'then' expected near '=' Been attempting to fix this, but with no success... EDIT: Alright so, this seems to work well, perfectly actually.... Code: function Create(self)
self.MaxHover = 4; --The maximum height above terrain the object will fly.
self.MinHover = 1; --The minimum height it will fly.
end
function Update(self)
self.Altitude = SceneMan:FindAltitude(self.Pos, 0, 2);
if self.Altitude < self.MaxHover then
self.Vel.Y = self.Vel.Y + 1;
elseif self.Altitude > self.MinHover then
self.Vel.Y = self.Vel.Y -1;
end
end ...but only when the AI is in control of the ship.

Re: Need the help of the lua gods! Oh yeah that was crap copypasta by me there, sorry.
I can't explain why the code doesn't work without AI, it should all be the same.

Re: Need the help of the lua gods! I've run into another problem. The ship's altitude doesn't adjust according to the min/max hover variables. It just chooses an altitude and stays there no matter what the variables are telling it to do.

Re: Need the help of the lua gods! I believe there is some sort of tilt hover system in S.A.Ws script if you still need.

It just chooses an altitude and stays there no matter what the variables are telling it to do. check the logic of that script... it seems that there is some problems. if self.Altitude < MaxHover then -- this "<" should be changed to ">" i think... and elseif self.Altitude > MinHover then -- this ">" should be changed to "<" ... in CC, the Pos.Y is bigger when the actual position is lower... it is based on screen coordinate system i think. and i'm not sure how is that Altitude calculated. will it always be a positive number?

Re: Need the help of the lua gods! I'm pretty sure the altitude is measure in pixels, no?
Anyway, the code ended up working after applying it to the dropship itself instead of the engines.
