Collision in specific point

Hi guys,

I have 2 sprite, first jackhammer and second rock, i need when jackhammer collision up the rock start a animation. any can help me?

If i set aimage points called Hit can i use for check that?

Have you tried it? Seems like you already know what you're doing.

Command:

When jackhammer collision to rock -> set animation

And is OK, but when can I set collision with image point 1 or 2

You can use jackhammer is overlapping at offset rock > offset x is jackhammer.imagepointx, offset y is jackhammer.imagepointy

That will move jackhammer to jackhammer.X + (the offset eh)jackhammer.imagepointX and jackhammer.Y + ((the offset)jackhammer.imagepointY, see if it overlaps, true or false, and moves it back to jackhammer.X and jackhammer.Y.

What you really want is ...

Offset at (x) = jackhammer.X - jackhammer.imagepointX

Offset at (y) = jackhammer.Y - jackhammer.imagepointY

Offset = a distance with world zero's at sprite.X and sprite.Y.

This is why I shouldn't answer posts before coffee, also I misread what was wanted, I don't even use that method at all. I normally use Pick overlapping object > jackhammer overlapping rock.imagepointx, rock.imagepointy.

Me 2 ... a very powerfull condition.

Especialy because. If you use 'overlap at offset' and you want to dedect a object only below that base object (while others can be on the side or on top) it will not work. Unless you size that base object before the overlap and size it back after the overlap.

Can you help me with that capx?

the problem is shape of rock

None of your animation frames have the same size, nor a origin on the same place, nor the same imagepoint in every frame.

Cant work that way.

That solves your collision thingy.

Dont really like the combination drag and drop/physics. Stone flys every way he likes. Drag gets interrupted by grafity.

thanks you, and for you how can i use gravity with drag mode ? because i tried to do that : when jackhammer overlapping arrow scroll to first point ( its one big layout), but drag not work
