object not collide properly and move it self

hello evryone... nice to meet you...

i just try construct 3 recently and many thing makes me confuse compare to my previous experience with other creator program. so, forgive me if I make a mistake...

as you can see in my file... i just create simple event. mouse clicked will move the player and create random box. the problems are:

1. when I "set position" of the player, the object move itself back to the last position. can't stay to the "set position" i set it for the object.

2. when the player and the block collide, it seems is not collide properly, there is a gap between block and player.

can anyone explain to me or maybe there is already any post about this? i need help. thank you everyone..

The answer to both questions is because you're using tile movement behaviour so the player moves on a grid of 32x32 and nothing in between. The first move is the player trying to get back to its grid position.

ahhhhh.... thank you very much... my mistake...

thank you for the info... now, i know what to do...
