c stack overflow (moving ComboPointPlayerFrame)

Hi,

im moving the Rogue Combo Point Bar like this:

Lua Code:

local function yOffset(Frame,y)
    local P = { Frame:GetPoint() }
    Frame:SetPoint(P[1], P[2], P[3], P[4],y)
end
 
hooksecurefunc(ComboPointPlayerFrame,"SetPoint",function(ComboPointPlayerFrame) yOffset(ComboPointPlayerFrame,91) end)

however i get the following error:

Code:

Message: C stack overflow

Stack: C stack overflow

its working fine though, but i cant fix it, whats the exact problem here?

It’s recursive. You attached a function that calls SetPoint to SetPoint itself. Find another function to hook to.

Yep. You are using SetPoint on each pixel of the y axis (same would be true if you also did it on the x axis). Try setting the frame to movable and moving or sizing. Once the frame has stopped moving, then GetPoint for the new position and save that to your SVs.

Shouldn't this work:

Lua Code:

local needs_to_setpoint = true
local function yOffset(Frame,y)
    if needs_to_setpoint
        needs_to_setpoint = false
        local P = { Frame:GetPoint() }
        Frame:SetPoint(P[1], P[2], P[3], P[4],y)
    end
    needs_to_setpoint = true
end
 
hooksecurefunc(ComboPointPlayerFrame,"SetPoint",function(ComboPointPlayerFrame) yOffset(ComboPointPlayerFrame,91) end)

i just anchored it to the playerframe , didnt worked the first time ive tried it , but it does now. well :banana:
