Enemy moves with only physics

Hi everyone.

This is my first post. I?ve been playing with construct for about only 2 afternoons, but I?ve really felt in love with it.

I?m trying to make a platform game without any platform behaviour (why? because I love physics and I love to try making things I still don?t know how to make thme).

I?m having a problem with enemys movements. Two issues:

• I?m not sure how to make a non playable character moves constantly in horizontal. I?m trying to apply forces or speed, and works well, but it gets broken when it collides with a wall for example.
• If an AI driven character collides with a wall, I apply a force depending on if it?s mirrored or not, I apply a system wait delay for mirroring it (if I don?t delay it wait, it doesn?t work :S). The result is not very good I think, because it can collide with the player too.

Thanks for all your help, and sorry for my bad english.

EDIT: Here is the capx, I was changing the var names to English to make them more learnable for you :). Of course, if you see there are thing that can be in a more reliable way, tell me please! I?m a totally noob on this <img src="smileys/smiley11.gif" border="0" align="middle"> jajaja. Thanks.

NOTE: Graphics and everything is only for learning, nothing is like it seems there :).

It would help us, to help you, if you would post your CAPX

Thanks, there it is, up in the first post :)

ok....now, what exactly is the problem? The NPC should move at a steady beat and bounce of the wall? What should happen if it colides with the player?

Like THIS?

The idea is that if the NPC hits the wall, it gets mirrored and turn into the opposite direction.

If it collides with the player, the player bounds a bit in the opposite direction of the collission.

That�s the first idea.

A second option or thing I would like to learn is that if the NPC collisions with the wall, the NPC bounds, and if he collides with the player, both bound in opposite directions.

But I think I�d be able to reach this one if I get the first one :).

Take a look at this CAPX

Oh man, that�s pretty simple.

I haven�t analyzed it at all yet (I�m at work) but it looks too much simpler than what I had.

It doesn�t work in the same way with a moveable wall with physics, but I think this happens because I have something to fix in the physics of that type of walls.

Do the forces have to be low numbers? I was applying forces too (100 instead), and you gain what I want more or less with a 0.5 value.

Thanks Wieshaupt!

since the force is apply every tick, it does not have to be big. Just play around with the numbers and see what happens....
