Restricting the player movement

How do I restrict the player movement? I need the player only move along a track (like a rail) with multiple junctions. Any help? Thank you.

I would suggest making your own movement events.

eg.

While Left Arrow is down

• >Set X to Object.X-2

While Right Arrow is down

• >Set X to Object.X+2

Are you thinking something top down like a train track? or a left and right?

Either way the Bullet behaviour is a awesome for straigt forward limited movement. I have a top down shooter where I ended up using bullet for movement instead of 8way. The reason being was that i am planning to use a analog stick.

BULLET is awesome. Just have it that at the junction, use a collision/ocerlapping to change the direction of the bullet object.

if you do a picture or share a sample of your idea we can help a lot more :)

Hy guys

Thanks for the reply.

I intend to restrict a player movement only, forcing that he can only move along a narrow path (like a rail or track) with multiple branches (like a maze). This way, he can go back and forth from any direction, including diagonally if necessary. A simple example attached

Thanks

How about something like:

if NOT player.overlapping.path

stop movement

snap player to path

if player.overlapping.path

enable movement

You get the general idea :)

Hi vee41

This restriction should be mandatory and not optional. As I understand your suggestion, it seems that the player does need to try to follow the trail. Is it?

This is what I had in mind: dl.dropbox.com/u/19921470/rails_example.capx

It 'sort of' works, what it needs to make it usable is proper turns and stuff. It's quite bad example really, just something I threw together to show what I meant :)

Thanks for the example, —

I get it, but it seems not work in diagonally. Is this the best solution?

I did some experiments with the 8-directions behavior and works too (I wonder why use the bullet instead of 8-directions). The problem is that the player is not stuck to the rail and does not change direction smoothly in perpendicular movements. If I move the playe horizontally and pressed the UP / DOWN in the middle of the line, the sprite loses the path reference and doesn't move anymore.

Please some more ideas and suggestions.

Thanks

Have you tried using solid invisible blocks to create a invisible barrier around each track? You can then set up custom movement or 8 directional, or even bullet. Car movement might be what you want for a train game though

Retro - Using invisible barriers gives me a problem (I'm trying to work out the same thing like the OP).

If I have a gap between walls/invisible barriers, and if my sprite is the same width as the gap, then the sprite gets stuck along the path! It wont move at all, unless I set the wall to Not Solid.

Of course I could make the sprite smaller, but then wouldnt I get jittery movement if the player presses up/or down?

Any solutions to the sticky wall phenomenon?
