problem with the collision of another object when it moves by mouse or touch input

A help porfa, I can make the object move in x or y and see it. But it does not recognize the collision is as if it were grabbing a mov set in the editor, it goes through the wall, I understand how the collision fuses but only seen from the main character the collision (ie the main character stops moving when it collides with an object ) but I do not locate when you grab an object and move it. I have a class of type pawn (a box modeled, and avilantado the collision block all), I do the cast to main character to call the location of the touch (same with the mouse) and add mov. The thing is that I do not recognize the collisions when I move it, it passes through the objects, I’m performing as the touch games for mobile. a help porfa
