Switching Player Sprites

[durnurd]

OK, here's a tricky one:

I created a sprite that follows the left wall.  (It's the player sprite).

I created a special function that switches the sprite to an identical one that follows the right wall.

Activating the function does not make the sprite go in the opposite direction, or find another wall to follow.  I'm not using the "switch "controlled by"" flag.  Anybody know why it doesn't work?  'Cuz I sure don't.

Uh oh... looks like time for stump the experts.  I will have to look into this in more detail when I have time.  Remind me if I don't reply before the weekend.

what happens, the player just stops when the function is activated? ...maybe the player has to be touching the right side of a wall to continue moving, like be surrounded by the walls

just a suggestion to try

What happens is, the player is moving along, moving along, and all of a sudden, when the function activates.....it keeps moving along, as if the function did not activate (I know it did, because I changed it to something else, and it did work).

Here's the project, if anybody wants to check my handy-work.

I have just a couple minutes to look at this this morning (I'm going to work at 4:30 am here, but only today.  ugh, too much to do.)  Anyway, first I noticed the functions weren't set up to activate at all.  They were not on the map and they were not global, so I'm not sure what was supposed to activate them.  I made them global and I made one of them (which didn't have any activation parameters) activate on the press of the right arrow.  When I did this I observed that the sprite didn't immediately switch directions, but next time it got to a place where it had to turn, it did.  My guess (without further investigation) is that a follow wall sprite will continue along it's current path until it hits a wall that it can follow.  When it's following a left wall and should be following a right wall, it won't turn until it hits a wall in front of it or to its right or behind it.

Oops.  I uploaded the wrong version, I guess.  They were set to activate on the press of the left/right keys, and they were global.  I guess I didn't save it after that.

But I hadn't noticed any turning around action when I tried it.  I'll have to try again later.  (4:30 AM!?  Sheesh!)

Being allowed to turn around only at concave corners, and jump to another wall only at convex corners, and being forced to always keep moving could make for an interesting game, though.  You'd have to be careful of those long empty walls if there was anything dangerous on them -- turn around and watch them for a while before you go accross them to make sure they're safe, and time your crossing well.  Kinda like being in outer space.  After you've pushed off, you're helpless until you hit something else.  That would be another cool game idea.  Every time you hit a wall the player can aim and shoot himself off the wall in a particular direction, but is then inert (can't control his movement) until he hits another wall (which is a feature built into gamedev -- you can easily detect when you hit a wall).  It'd probably require some scripting, but relatively simple.

Interesting gameplay style.  Sounds like something that hasn't been done before.  But then, coming up with a game to go around it, that's the hard part.
