Is it possible to make a pushable placeable? Statue that slides around by being pushed (Dragged)by the pc?

[CID-78]

not like you do in zelda and that kind of adventure games. you can move placeables with scripts. ie create/destroy or give a creature the apperance of a placeable and allow it to move around.

I hadn't thought of the creature option. Currently working on a mirror I want the player to twist, so I set waypoints at the two possible angles, then destroy one mirror while creating the other. Even though they're the same object, I made the two unique so that I can give them different descriptions to describe the changed reflections. It's not ideal as you see one fade out while the other appears, but it does the job, and I think most players would be forgiving considering the limitations of the toolset.

Ya creatures should work. Thanks for your input.

Although you cannot move them, you can rotate them without having to recreate them like that. SetFacing will work.

You could consider using a visual effect to conceal the swap. Cheesy, but does the trick.

If you don't mind using a bit of custom content, creating several visual effect copies of the placeable with a simple sliding animation could look really cool, and far smoother than changing positions by script. You'd choose which way to move based on the angle between the creaturing using the statue and the statue itself.

See, now I want to try it too, darn it

How about a placeable that doesn't actually move but has an animation (as in, Activated/Deactivated or Opened/Closed) that makes it appear to move. Is that not doable?

Imagine for example an "invisible" chest on it's side whose "lid" is a bookshelf which when set by click or script to open/activated slides out and away from the wall. No need for fade-in/out or other it just slides. No good?

(Edit: I fear I may have misunderstood the OP, though I'm still curious if this has been thought of or done.)

Hm. Having just implemented the basics of statue pushing myself (I did say you'd made me want to try it) by having the statue move one square of a small grid along whichever axis the player pushes it from, I've noticed a few problems.

Firstly, if the placeable blocks movement, then the player will always move to a certain position around it before using (namely, where the use node is in the model). You can get around that either by adding an empty .pwk for the placeable, or by simply placing it 50cm to a metre below ground level, so the placeable's walkmesh gets ignored by the game. Either method should make the player able to push from any direction.

Secondly, the fading animation placeables use when created and destroyed seems to be unstoppable. Which means adding a sliding animation on top might look a little weird. But I haven't taken a shot at implementing that yet.

I did try to post my code, but these forums hate me.

I'm pretty certain you can place multiple use nodes - I've seen some of the Bioware placeables have as many as six.

[_six]

Having had a mess around with the use nodes, it seems no matter how many you add, only two are useable. For some reason the first and last declared in the model are used, and any others ignored. I might be creating some kind of other problem with the pwk, I suppose, but I tried it several times.

Very strange.

My solution was to make a minimal amount of the model block the player and include only one use node in the centre. As it is using from all sides works fine, albeit with the player's leg sticking into the statue a bit.

Darn you, visual effects. Darn you and your glowyness.

That's really not bad _six.

[CID-78]

do the visual effect just slightly bigger so you don't see the popup of the static statue.

[Pstemarie]

Nice work Six

Wow. Now how did you do that?

Haha!  Learn something new every day.

I just tried doing SetPosition for placeables, and it did work!
With the new NWNX API it's just one line of C++: oObject->SetPosition(vPos, 0);
Placeables don't move smoothly as NPCs, though: in the client it appears if it has disappeared and then appeared in another place.

Brace yourself 

Firstly, changed the statue model and pwk so you can activate it from all four sides (by putting the Use node in the centre, and making sure the walkmesh is small). Secondly, I took the placeable model, and created four vfx files, one for each direction of it moving.

The script for moving around, well, I tried to post it on the forum, but after getting annoyed at formatting I put a txt file of it here.

To check for the statues being in the right place, I use a pseudo heartbeat fired from a trigger's on enter around the room. It basically uses the same IsInSq function to check if the statues are within one metre of some waypoints I placed. I tried to use GetIsInSubArea with triggers instead, but that apparently only works for creatures (or it didn't work how I used it, anyhow).

Out of interest, does that mean you get the fading in/out effect?

Edit: Just noticed the video  I'm curious, is there any way through NWNX to fire a script on every frame render? Not much use for a SP mod, but...

Also, uploaded a video of the 'final' version of the statue sliding I came up with for my mod. Excuse the noodling around, I had set it up to involve weather as well as the statues, and it conveniently started raining while I was on the way to the rain god's altar.

Frames are rendered on the client, while scripts fire on the server.
I can hook rendering functions in the client, but what for?

[_six]

Just thinking on the lines of what might be possible in terms of simple animations with placeables.

[AzurDraak]

@ _six

I notice in your video that the statues change orientation during transition. Is it possible to retain facing in the vfx files?

Hehe well I guess this is well out of the scope of my current abilities. Thanks for the info.

(damn learning curve!)

Heh, you know, if you take out the vfx bits, that script alone should handle most of it for you, for one or multiple moving statues. Just change the tag "TombStat1" to whatever yours are, and put a waypoint in the centre of the area you want to be able to move it around with the tag "StatPuz".

You mentioned altering the placeable and vfx files, are you going to put your hak file with modle and vfx changes and a demo in the nwn vault?

Other wise the script that you gave can be altered to:
When player use placeable the get a conversation to chose direction to push it and then....

Are you even thinking of developing this more?
