My Bugs. two different buttons;

The 2 buttons do not work the same way (In the game), I have to change the buttons on my touchpad, to be better build high houses. but when I leave button 2 (for which I got used to) to attack, and button 1 to build; I can only attack, I can not build because I need to jump to put the block, but it does not work. even pressing hard; Solve it.
