求助 shader在安卓上报错 PC上正常

Cocos2d-x
#1

自己扩展了一个shader效果 版本3.8 lua
就是能够做一个任意位置的圆形透明 在PC上表现正常 上了安卓以后报错 可能报在任何地方 最多是在CCTexture2D的initWithMipmaps

lua创建代码
local CenterPos = self.tower.bgBtn:getParent():convertToWorldSpace(cc.p(self.tower.bgBtn:getPosition()))
local CenterSize = self.tower.bgBtn:getContentSize()
CenterPos.y = display.height - CenterPos.y
local baselayer = self.widget:getChildByName(“baselayer”)

local TestBg = cc.Sprite:create("Bg/loginScene.png")
TestBg:setPosition(cc.p(1366 / 2,768 / 2))
baselayer:addChild(TestBg)

local gl_Program = cc.GLProgram:create("shader/shader_SpriteMisty.vsh","shader/shader_SpriteMisty.fsh")
gl_Program:bindAttribLocation(cc.ATTRIBUTE_NAME_POSITION,cc.VERTEX_ATTRIB_POSITION)
gl_Program:bindAttribLocation(cc.ATTRIBUTE_NAME_COLOR,cc.VERTEX_ATTRIB_COLOR)
gl_Program:bindAttribLocation(cc.ATTRIBUTE_NAME_TEX_COORD,cc.VERTEX_ATTRIB_FLAG_TEX_COORDS)
gl_Program:link()
gl_Program:updateUniforms()

local RLenth = math.sqrt( math.pow(CenterSize.width / 2,2) + math.pow(CenterSize.height / 2,2))
gl_ProgramState = cc.GLProgramState:getOrCreateWithGLProgram(gl_Program)
