How do I lock an Object within boundaries of a Moving Object

Hey,

I am trying to make a train game, where the player can board a moving train. Right now the train is simply moving along a path continuously.

I want the player to be able to move around freely when on the train cart and as the train moves and changes directions, the player should move with it.

I tried to set the X and Y coordinates of the player to match that of the train, but of course this would mean the player is locked onto the train (and not able to move freely around the moving train cart the way that I want).

Does anyone have any ideas how this could be done?

Thanks in advance.

Need.. help... from.... those of superior intellect

maybe trying creating an invisible border that is solid and the player cannot collide with along the edges of the train?

Although that would contain the player from being moved out of the train, that still wouldn't work because the player would constantly be being pushed to an end of the train depending on its direction.

I was unable to download your capx. Could you reupload it or post it on Dropbox?

Sure, sorry about that. Here is an updated link (but they both should work - that was odd).

Thanks in advance if you can figure it out!

This isn't a real solution, but it works, a litte bit. As long as your player is on the origin of your 'train' it works.

But if not and the train turns you will fall of and I don't have any solution for this. I tried a rotation matrix to calculate the postion of the player when the train turns but that doesn't work.

In your every tick event

System every tick -> Player set angle Train.angle

" " -> Player Move forward Train.Pathfinding.Speed*dt

Does this solve your problem?

Asmodean - good attempt I like what you were thinking but unfortunately this locks the players Angle to the Angle of the Train.

LittleStain thank you! You've solved a huge problem for me. I initially had a similar idea to use the Train objects OldX and OldY but I couldn't for the life of me figure out how to work out the changing of the angles. Thanks again!
