Unity3D_ Class fishing project, control the distance between collision walls to adapt to different models

background , Recently took over a project , Fishing like game , The demand is that the bullet can rebound in the surrounding wall after being fired , You can refer to another article about rebound . Because the screen aspect ratio of different models is different , Therefore, it is necessary to adapt to the distance between walls . as everyone knows ,U3d Of Camera When the camera changes the viewport , The upper and lower edges are unchanged , Only the left and right edges will be close to or away from each other . The same goes for mobile screen , The left and right edges of the widescreen mobile phone are far away one after another , The left and right edges of tablet phones are close one after another . Therefore, after knowing the screen resolution of the mobile phone , Next, just change the yellow arrow wall

 

--  The wall adapts to different screens , remarks ：GreatWallMgr.LeftWall And GreatWallMgr.RightWall Left and right walls 
function GreatWallMgr.InitAdaptionWall()

    --  Benchmark scale 1136：640 == 71：40, My project is based on 1136：640 Adapt to different resolutions for Standards 
    log("Height: " .. tostring(curCamera.pixelHeight))
    log("Width: " .. tostring(curCamera.pixelWidth))

    local curHeight = curCamera.pixelHeight
    local curWidth = curCamera.pixelWidth

    local Dwidth = 71*curHeight/40 --  Difference value 
    local Pwidth = (curWidth - Dwidth)/Dwidth --  Percentage of actual width to base width ,+ To exceed the benchmark ,- Is less than the benchmark 

    local leftPos = GreatWallMgr.LeftWall.position
    local rightPos = GreatWallMgr.RightWall.position
    --log(tostring(Pwidth) .. " Pwidth")
    local wallDis = Vector3.Distance(leftPos, rightPos);
    --log(tostring(wallDis) .. " wallDis")
    local dPos = wallDis * Pwidth / 2
    --log(tostring(dPos) .. " dPos")

    GreatWallMgr.LeftWall.position = Vector3(leftPos.x - dPos, 0, leftPos.z);
    GreatWallMgr.RightWall.position = Vector3(rightPos.x + dPos, 0, rightPos.z);
