Controlling texture shades

[Grogyan]

Okay, okay, I just reminded myself that I wanted to get some idea of how to change the colour/shade of a texture on an object sequentially at the push of a button.

It was one of the ideas that I wanted to include in the contest but still havn't got round to it, mainly because coding of any sort with python hurts my head.

There are several states, gray, red, green, blue/yellow and white, which will form the basis of a puzzle.
The goal is that the texture will stay the same, but the shade/colour of the texture would change, any ideas would be very grateful on how to implement this without python or with little python coding.

I understand that some python is needed because of using SDL states, but this idea has really stumped me.

Ok, this is what I'd do:

I'd either have a light that affects the object's color and then control the light's hue.

or

I'd have actually duplicates of each object(with different colors) and then hook them up to turn on and off.

If you're into python code(like I am), here's the code for making an object invis/vis:

Code: Select all

##Note:  You'll need to import Plasma and PlasmaTypes at the top of your file, here's the code:

from Plasma import *
from PlasmaTypes import *

##code to make object invisible

objName = "<your objectname>"
obj = PtFindSceneobject(objName, PtGetAgeName())
obj.draw.disable()

##code to make object visible


objName = "<your objectname>"
obj = PtFindSceneobject(objName, PtGetAgeName())
obj.draw.enable()


Ok, here's the code to make a lamp change color:

Code: Select all

lampName = "<Your lampname>"

r = 1.0

b = 1.0

g = 1.0

intensity = 1.0

obj = PtFindSceneobject(lampName, PtGetAgeName())
PtSetLightValue(obj.getKey(), r, g, b, intensity)

There we go. If you don't want to have to program in python, I can help a bit with the coding. Just PM me.


SDLs aren't really the meat of thing, mostly what they're used for is to save the state if you leave the age, I don't usually use them.

If you have a clickable puzzle, Python's mostly what's going to be running it.

There are some inside-the-prp non-python stuff you maybe could do, but the documentation is hard to find.

If anyone can think of a better way of doing what Grogyan wants his age to do, please post.

I was thinking on the same lines today, that maybe the best way to go is making 4 copies of each mesh with different colours.

Don't open for casual reading as this spoiler can contain puzzle mechanics Show Spoiler

There are 3 crystal pillars with 1 of 5 possible states, initially they'll all be gray, and once the puzzle is complete they'll switch to white.

This was where I had got up to and was starting to hurt my head, because of the difficulty knowing which mesh is the right one to toggle on, and they'll be clicked on sequentially
For example 1 crystal would be
touch 1 Toggle from Gray to Red
touch 2 Toggle from Red to Green
touch 3 Toggle from Green to Blue
touch 4 Toggle from Blue back to Red
If code not complete in n seconds all crystal pillars revert back to Gray

A code of the various pillars will also mean that each pillar will have 2 placements in the entire code sequence
eg
Numbers represent the pillar number, while the row underneath it is the sequence that they have to be in
1 2 3 1 2 3
R G B R G B
Other things will happen upon the correct sequence too

After reviewing what needs to be done, timers, counters, trigger regions, clickables, sound triggers, that its quite likely that i'll need help coding it in.
But the main thing that has been racking my brain is switching the colours of the texture on the crystals as opposed to having many copies of the same object

Hmm, let me do a little test with python and lights.

I have a few other fixes and additions before doing this hard bit.
Let me know how you get on

[Lontahv]

Do you have the crystals in the age's blend? It's easier for me to download the blend, alter it, then send it back to you. Rather than having to make a tutorial, or a template.

If you're going to have multiple copies of the same crystal, do a bit of work on each of the states you want it in, then when you send me the blend, I can just program. And then alter the age to include click regions etc. and a .pak.

Wow thats great.

Yeah the crystals are in the .blend file, though i'm not to sure what you mean by states, as at this moment the best I can do is jot down all the states I need or I think i'll need, which I think I can do easily enough in SDL format

I have quite a bit of work to do yet, but i'll get onto it more this week if I can.

FYI, when I/we, finished the Age, I plan on submitting it for everyone to look at, recompile it etc from the .blend, with textures and sounds and scripts.

I feel as though I need to do this, as there really isn't a reference Age that takes a lot of things into account, especially with the recent features in the plug in.

I still havn't done any lighting yet, still something I have to work on.
