我想在同一点生成两个物理对象，然后通过施加力来移动一个物理对象，但是当一个对象移动时，它会与另一个物理对象发生碰撞。我不能将另一个对象设为非物理对象，因为这些对象会进一步相互碰撞，但最初它们不能碰撞。我所做的一些编码部分如下......请提出任何想法..谢谢

local obj2
local physicsbody1= { density=0.1, friction=0, bounce=0 }
local physicsbody2= {density=10.0, friction=0, bounce=0.1, radius=25 }

local function createobj2(_xpos,y_pos,_id)
obj2=display.newImage("obj2.png")
obj2.x=_xpos
obj2.y=_ypos
physics.addBody(obj2,physicsbody1)
end


local physicsObjStatic=display.newImage("img1.png")
physicsObjStatic.x=450
physicsObjStatic.y=200
physics.addBody(physicsObjStatic,physicsbody2)


    local function Shot( event )
        local t = event.target

        local phase = event.phase
        if "began" == phase then
            display.getCurrentStage():setFocus( t )
            t.isFocus = true
            t:setLinearVelocity( 0, 0 )
            t.angularVelocity = 0

            target.x = t.x
            target.y = t.y

            startRotation = function()
            target.rotation = target.rotation + 4
            end

            Runtime:addEventListener( "enterFrame", startRotation )

        local showTarget = transition.to( target, { alpha=0.4, xScale=0.4, yScale=0.4, time=200 } )
            myLine = nil

        elseif t.isFocus then
            if "moved" == phase then
                 if ( myLine ) then
                    myLine.parent:remove( myLine ) 
                end
                myLine = display.newLine( t.x,t.y, event.x,event.y )
                myLine:setColor( 255, 255, 255, 50 )
                myLine.width = 8

            elseif "ended" == phase or "cancelled" == phase then

                display.getCurrentStage():setFocus( nil )
                t.isFocus = false

                local stopRotation = function()
                    Runtime:removeEventListener( "enterFrame", startRotation )
                end

                local hideTarget = transition.to( target, { alpha=0, xScale=1.0, yScale=1.0, time=200, onComplete=stopRotation } )

                if ( myLine ) then
                    myLine.parent:remove( myLine )
                end
createobj2(t.x,t.y)
obj2:applyForce( (t.x - event.x), (t.y - event.y), t.x, t.y )
            end
        end
        return true
    end

您应该在拖动对象时将其临时更改为运动学而不是动态的。运动学对象不会产生碰撞。
