Not sure if im doing something stupid or if its a bug. I have been trying to use dbIntersectObject() to position a model on the floor (which is made up out of planes) and I do this by raising my player 30 units from where they were then calling an intersectobject from their point to 100 units below them and move the character down by the distance returned by intersectObject.

Except what happens is my player model stays fixed where it is without moving at all (im guessing IntersectObject() is returning 0) even if i walk off the ground planes and into nothingness. If i however i change the intersect call to look 100 units ABOVE the player instead of below then she falls into infinity forever.

take a look at this code:



now have i written something stupid in there? or is this a bug?

this has been bugging me -alllll- day ><;

I think the problem is that you should supply IntersectObject with the id of the floor object, not of the PlayerChar itself.
When you intersect with 100 above itself, IntersectObject(playerId..) will always find that the distance is 100 so the player will fall indefinitely...

Note: Each time I post something to the forum, I am informed that "Thank you for your post. As a new member your post will NOT appear until we approve it - read this to find out why." and my post appears hours later. When will I be approved automatically ? Is there anything to do for that?

Can you insert a consoletext so you see what's the dbIntersectObject() is returning? Maybe the function is broken.
Just a thought, can't really help yet.

Okay, a guy called Artus sent me an email with a solution to the problem because posting on the forums is a bit bugged for him.

Just wanted to mention his name here so he gets proper crediting, it really helped me out

For those interested, I had to swap the player object id with the id of the floor im trying to detect XD

Thanks again, Artus.

The forums aren't bugged. It's the standard post approval system that *all* new members go through.

hmm, post approval isnt a bad idea. But for such a system you really need a bigger base of mods that are active longer... waiting a few hours for my first post would probably of made me leave the community pretty snappish before because I would of had no help when i needed it most, on my first day. lol.

I also fully agree with the principle of approval in order to protect the forum from spam-like posts. However, I have sent 5 or 6 posts since the beginning of March, and I still have to wait for approval each time. This does not favour reactivity when someone is stuck with a problem you have a solution for. I just wonder under which criterions or after how long is a member considered as "not new".

I can't tell you ... but you are probably not too far off fulfilling the requirements - they are fairly light.
