I'm having an issue with a custom script that won't load properly when transitioning between campaign maps (I'm using this for transitions). Basically the script calculates the height difference between the units Z value and the ground (or something), and then sets the camera height accordingly.
I have made two test campaigns.
I have made two test campaigns.
- In this test campaign (Test Campaign 1) the script runs once on map initialization, and again every time a saved game is loaded. In this version the issues starts when you re-enter a map for the second time and on all subsequent entries. The camera will zoom in/out really fast in some areas, and then stutter in other areas.
- In this test campaign (Test Campaign 2) the script only runs once on map initialization, and is never ran when a saved game is loaded. The script completely stops working on all subsequent entries.

Custom script: local u=udg_MyUnit TimerStart(CreateTimer(),0.03125000,true,function()if not udg_Indoors then SetCameraField(CAMERA_FIELD_TARGET_DISTANCE,1600+BlzGetLocalUnitZ(u)-GetCamOffset(GetUnitX(u),GetUnitY(u)),0)end end)
Code:
do
local cameramapLoc
local mapMinX, mapMinY
local offsets = {}
local GetCamOffsetInitGrid
local function GetCamOffsetAt(x, y)
local idx = y*yfact+x
local res = rawget(offsets, idx)
if res then return res end
res = GetCamOffsetInitGrid(mapMinX+256+512*x, mapMinY+256+512*y)
rawset(offsets, idx, res)
return res
