My objects are instantiating at x axis 0 and not where I click. As you can see in the below first image that when I Click at a point on the game screen and drag the wall (shown in Purple) from that point, after I let go of the wall at point B, the actual objects that I want are not instantiated at the wall position and along the length of the wall. Instead, you can see in the second image that the objects (shown in Purple and Yellow) are instantiated on and from a point I did not click. Is there any way to solve this? I have attached my script below. Please I need help. Thank you.
