Lua script request.

Could someone write a script that locks the camera in TA camera at a specific zoom and rotation. Also could the camera stay locked on a specific unit?
Thanks in advance.

You can change the angle using Ctrl+Mousewheel... Is that what you're after?

Don't post such an answer, or Smoth will raeg about how useless it is to post requests here again.

does that lock the camera to taview? does it set distance/angle? Does it set the camera to follow a unit? No, that is just turning the ta camera.
I would not make this request if I didn't have a good reason.

What is the unit you need the follow? How does widget (or gadget?) is given its ID? Will that unit change? Is it for a game where each player only has one unit? What if that unit die? Lock on death place or allow free roaming? The angle and height, hard coded or parametrable? Which way are passed the parameters? I assume some elasticity between the camera and unit movement would be nicer than stuttering?
From having tinkered with xyz's "spectator mode" widget, I know all you need is to periodically issue the commands:
Spring.SetCameraState({name=ta, mode=1, px=UnitX, py=0, pz=UnitZ, flipped=-1, dy=-0.9, zscale=0.5, height=999, dx=0, dz=-0.45}, TRANSITION_DURATION)
Spring.SelectUnitArray({UnitID})
Spring.SendCommands("track") -- "trackoff" is the command to stop it
Spring.SelectUnitArray({})
Or maybe if you're less conscious just:
Spring.SetCameraTarget(UnitX, 0, UnitZ, TRANSITION_DURATION)
So 90% of the code would be interfacing. And only you know what kind of interfacing you want. Because only you know the purpose and environnment of that Lua script.

Should maybe mention that I already gave him one.

No, it was him that should have mentionned.
Here's the one I'm using now:
Code: Select all
function gadget:Update()
local u=GetTheOne()
if u then
-- Focus on the unit
Spring.SelectUnitArray({},false)
local x,_,z=Spring.GetUnitPosition(u)
local _,v,paused=Spring.GetGameSpeed()
v = paused and 0 or v
local vx,_,vz=Spring.GetUnitVelocity(u)
local r=UnitDefs[Spring.GetUnitDefID(u)].maxWeaponRange
Spring.SetCameraState({name=ta, mode=1, px=x+9*v*vx,py=0, pz=z+9*v*vz, flipped=-1, dy=-0.9, zscale=0.5, height=2*r, dx=0, dz=-0.45},1)
else
if not Spring.GetSpectatingState() then
-- Focus on the start pos
Spring.SelectUnitArray({},false)
local x,y,z=Spring.GetTeamStartPosition(Spring.GetLocalTeamID())
Spring.SetCameraState({name=ta, mode=1, px=x, py=0, pz=z, flipped=-1, dy=-0.9, zscale=0.5, height=1200, dx=0, dz=-0.45},5)
end
end
end
Notice how it compensate the unit speed and scale to weapon range. This does well for the purpose I wrote it for. However:
Is there any way to lock a camera, in the sense of making it obey Spring.SetCameraState and Spring.SetCameraTarget strictly and ignore any user input related to camera?
Because I want to do ingame cinematic intro to my mod, and I don't want my script to have to fight back against mouse pointer idling in the corner or user clicking on minimap.
