I have a character, and a castle. Both 3D objects. The character floats in midair while standing and walking. The character walks through the walls of the castle.
How do I make him walk on the castle floor, and how do I prevent him from going through walls?

Look into something called 'Nuclear Glory' on these forums or in Google, it is by far the easiest way to do what you are talking about.

Another way is to split the castle into floors and wall (seperate objects).

Hi GreenFox,
You have asked a very popular question. If you try a search you will probably be surprised by the number of possible solutions.

Mean while here are some hints:

Use the object intersection command if youre interested in making it yourself and not using Dll's. Or you could check out COLD in the WIP boards, its a function for this, almost complete but should suit your needs for now.

Have you thought about positioning your objects Y position to the level of the ground.

Our aim is to keep the loo's clean, your aim can help.

Say your 'castle' is object 1, and your 'character' is object 2.

Position the character so that his feet is a little *ABOVE* the floor, and then change your code like this:

Quote: "` Say this was your 'move forward' code.
`Remember to turn collision on.
`I don't know what shape your castle is,
`so use this for now:
set global collision on

if upkey()=1
`Move the character forward
move object 2,1.0
`If he's now touching something, move him back again
if object collision(2,1)=1 then move object 2,-1.0
endif
"



Y'see, if you move the character back again before the next 'sync', as far as the player is concerned, the character hasn't moved.. at all.
There's probably better ways, but it works great for me. ^_^

O yeah, and you position his feet above the floor as otherwise as far as the game is concerned a 'collision' has occured, and he'll be glued to the spot like a glued thing.

Just send an intersection ray below the user's feet, if an intersection occurs move the user up by like .1. Works perfectly.

To GreenFox:

Try this example.You got a castle and camera(FPS-engine).Put yor
character in the camera coordinate and camera push back to chase the player.
This code uses Sparky collision DLL and it works nice.
Any question at: [email protected].
Good luck!
Toggy.

@ blanky, your idea doesn't work, sorry, possibly because my castle is a 3D X file object that I load into the game, scale, and position.
Thanks anyway.

@ RUCCUS, I dont know how to code that stuff, can you please do it for me if its not too much work?

Fox

To get started, try something simpler than your castle. Once you can collide with a box, you use the same idea for all the walls.

Try using Sparky's Collision DLL... it's really helpful, and is almost better than Nuclear Glory's Collision DLL.
