Ladders anyone?

#21 THANKS BADGUY!!!! Your help will not go un-noticed I assure you!

#22 Okay, badguy didn't send the code so I talked to Mark Harmon about how I might go about implementing ladders and elevators. He suggested a "Lifter" object that the user mounts to that takes him up and down. This last weekend I copied the vehicle class and stripped it down to the bare minimum. I renamed this class Lifter and clamped all movement in the x and y direction. I also remapped y motion to z motion. I also have collision code that won't allow the user to pass through areas he shouldn't.

SO, I have this working now. I place a lifter object at the base of my ladder, the user collides with it, mounts it, goes up when you are pressing up, down when you are pressing down. I have dismount logic too, but I am going to play around with this some more to get it right.

#23 sorry guys i got Real tied up this weekend with other obligations
:(

I didnt forget but I spread myself out to thin.

your idea seems ok. not quite All the control I wanted to see on a ladder but it will def do better than lots of games ive played :)

#24 Cool Kurt!

#25 Hey Kurt
I just got back from E3 in LA. Talking about pumping someone up!! WOW!!

Sounds like a great idea. I have not had very much time to look at this. If you don't mind could I take a look at it? I have to be able to implement ladders also. I would also share anything else I could come up with.

Thanks

#26 I am still kicking around the best way to dismount. i am leaning toward triggers. Once I have that figured out I would be glad to give you the code so that I could get some feedback. I also might take into consideration left and right movement so that if the user decides to dismount halfway up he can. I will keep you posted.

#27 Thanks Kurt

If I can help you do anything just let me know.

#28 Okay, I am willing to give the lifter object to whoever wants it. I am kind of anxious to see how people will handle dismounting. Basically you will just have to add this object to the engine and then define the object data in script.

#29 Great! My email is jackie@powerzones.com or jackie@swris.com. If you could send it to me I will be more than happy to check it out and let you know what my thoughts.

Thanks Kurt!

#30 I think bassically it shouldn't be nessesary to mount players to the lift but rather put an trigger at the top of the lift and include a special ontop object to the lift.

When players enter the lift they just gain an upward/downward motion equal to the lift.

Also I noticed that staticshapes moving up or down slow enough will adjust the players height ontop without any extra code.

But anyway.. wouldn't a simple jump create sufficient dismount ability?..

#31 Okay, I have finished the lifter object. It is basically tuned to be used for ladders but with some tweaking it could be used for elevators. I am using triggers on my ladders to dynamically create a lifter object, set the animation to climbimg, and play a dismount animation for when the user gets to the top. Looks really good. Sebastian is going a different route I think so you should have some choices in the future. If you want the object just let me know. Maybe I will create a resource if I get time. Don't know if this should become part of the engine or not.

#32 Hi Kurt. I'm really curious to try this, please.

Thanks !

#33 Hey Kurt. I'd like to see your updates. I am working on some things right now but I am hoping to get to this by next week. I'll keep you posted.

Thanks

#34 Kurt...I could use the leap on this.

#35 Sent the zip to you guys. I am going to upload it my site for those of you that might want it in the future.

:)

#36 Kurt,

Thanks mucho ! I'll try this tonight(family ). A first look at it and it seems really well done. I'll give you feedback.

#37 A couple of things. I use a transparent geosphere as my DTS lifter object. I model it very small. This seems to work very well.

The code will automatically start playing a climbing thread if you have one when a player is mounted. I need to add a climbing root animation for the case where you stop on the ladder. I am doing that this weekend. I might also add code that will allow for a left or right movement. Maybe just use a tolerance.

One other thing that really needs to be done is to expose more parameters to the console. Right now acceleration is hard coded.

Anyway enjoy!

Kurt

#38 Kurt, sounds great! :)
Got a link for us where to download it? ;)
thx a lot!

#39 Fixed the problem where the player wasn't going into root climb animation when stopped on the ladder.

Find the line:

if( m_player )
           m_player->setActionThread(  0,false,false,false,false,false);

This is where I am going into the default root animation (if you are not moving) which is not quite what you will want to do. You will want to create a root climbing animation. So you will have a climb animation and a root climb animation and , if you choose, a dismount animation for when the player dsimounts the ladder. Here's the link. If you improve upon it, let me know! ;P

#40 Kurt,

This is working great. Really cool ! A new vehicle kinda, hehe. My actual project is vehicles only (car game) so I can't use it like it is but for FPS games, it's really usefull. I'm sure a ressource would be really of interest for the community. I will maybe try to make vehicle's elevator with it :) (I'll tell you if I do). Again, thanks mucho, nice one !
