How do I make an object stop in collision?

Sorry for the noob-ish question, but everyone's got to start off from somewhere, right?

So, I'm using two active objects, one of them is invisible. I have a collision event between the two. I don't know what to do to make the first object (which is my character) stop when it hits the second object (which stands for a house). They are both marked as static objects, so the movement options are all greyed out but even when I made the character a bouncing ball and used "stop", it still didn't work. So what do I do?

If they are static, they don't move so they can't collide. Unless you are using a custom movement. If you are, it would help to know how do you move the objects.

Ok I took a pic of my screen to show you what I'm doing with the movement:



I'm trying to learn more about custom movements, the presets aren't enough to do what I have in mind so if you have any suggestions, it would be very nice.

Btw some of these conditions (epsecially in the start of frame event) are just left outs of failed attempts.

If you're using a custom movement that involves manipulating the X and Y positions of an object directly (which I think you are, judging from the events) then, further down the event list than any event that moves the objects, you have to check whether the two objects are overlapping and, if so, move them away from each other again so that they are no longer overlapping by the time the frame updates.

From what I can gather, you're using Alterable Value B as a flag to detect when the player is moving? You could change the value it's set at to distinguish between the left and right keys being held, and insert events like:

+ Player Object is overlapping Wall
+ Alterable Value B("Player") == 4 [Or some other condition to check that the player is heading left]
-> Add 3 to Alterable Value X [To set the player back to the right by the same number of pixels that he moved to the left].

And a similar event for the movement to the right.

Ha that works, you make me so happy, thank you so much! I've been working on the graphics for days now and I can't wait to start putting them into action.
