Overview
|
|
========
|
|
|
|
|
|
Why ?
|
|
-----
|
|
|
|
It allows the user to see a graphical representation of the entity in the 3D view (maybe 2D views later) where the entity would just otherwise be a non-descriptive coloured box.
|
|
|
|
It is designed to be used with the entity view set to WireFrame (as the sprite images are rendered in the middle of the entity's bbox).
|
|
|
|
How ?
|
|
-----
|
|
|
|
Implemented as a model module, without any ISelect stuff.
|
|
|
|
For an entity to use an image (instead of a model) you just update the entity defintion file so that the eclass_t's modelpath is filled in with a relative path and filename of an image file.
|
|
|
|
e.g:
|
|
|
|
baseq3/scripts/entities.def
|
|
===========================
|
|
|
|
\/\*QUAKED ammo_bfg (.3 .3 1) (-16 -16 -16) (16 16 16) SUSPENDED
|
|
...
|
|
-------- MODEL FOR RADIANT ONLY - DO NOT SET THIS AS A KEY --------
|
|
model="sprites/powerups/ammo/bfgam.bmp"\*\/
|
|
|
|
|
|
valve/scripts/halflife.fgd
|
|
==========================
|
|
|
|
@PointClass iconsprite("sprites/lightbulb.spr") base(Target, Targetname, Light) = light : "Invisible lightsource"
|
|
[
|
|
...
|
|
]
|
|
|
|
What image formats are supported ?
|
|
----------------------------------
|
|
|
|
This module can load any image format that there is an active image module for. For q3 this would be bmp, tga and jpg. For Half-Life this would be hlw and spr.
|
|
|
|
Version History
|
|
===============
|
|
|
|
v0.1 - 27/May/2002
|
|
- Created an inital implementation of a sprite model plugin.
|
|
According to the powers that be, it seems creating a model
|
|
plugin is hackish.
|
|
It works ok, but there is no way to attach models (sprites if you will)
|
|
to non-fixedsize entities (like func_bombtarget)
|
|
Also, I can't get the alpha map stuff right so I had to invert the alpha
|
|
mask in the spr loader so that 0xff = not drawn pixel.
|
|
|
|
v0.2 - 10/March/2003
|
|
- Updated to coincide with Radiant 1.3.5 test builds. Also, I made sure it worked
|
|
under quake3 and it does.
|
|
|
|
v0.3 - 10/March/2003
|
|
- Added about box.
|
|
|
|
ToDo
|
|
====
|
|
|
|
* make sprites always face the camera (is this done in camwindow.cpp ?)
|
|
but only if the entity model doesn't have "angle" keys. At the moment
|
|
it's better to rotate the model with the angles.
|
|
|
|
* maybe add an option to scale the sprites in the prefs ?
|
|
|
|
* maybe convert to a new kind of class not based on model.
|
|
|
|
* allow sprites on non-fixedsize ents
|
|
|
|
* fix reversed alpha map in spr loader
|
|
-> is this actually broken?
|
|
|
|
* allow an entity to have multiple models (e.g .md3 and a sprite model)
|
|
and allow the user to toggle either models on or off.
|
|
|
|
* dynamically add the api's depending on what image loading modules are
|
|
supported by radiant.
|
|
Currently, we hard code to the list in "supportedmodelformats" (see below)
|
|
but, all these extensions are stripped when the actual image is loaded.
|
|
current the bit of code that decided what model api to use needs reworking
|
|
as it decides by looking at the extension of the model name, when in fact
|
|
we don't even need an extension.
|
|
|
|
Previously the code fell though to use this model as the default model
|
|
plugin, but that also has issues.
|
|
|
|
what it means is, in the .def files you must specify an image filename
|
|
that has one of the extensions listed below, but in actual fact radiant
|
|
will use any available image module to load the image.
|
|
|
|
|
|
e.g. you could use a model name of "sprites/target_speaker.tga" and have
|
|
a file called sprites/target_speaker.png and it would be correctly loaded
|
|
even if it not listed below in "supportedmodelformats".
|
|
|
|
So, currently in the .def files you can just use the name
|
|
"sprites/target_speaker.spr" and it will load the file
|
|
from "sprites/target_speaker.*" which is what I propose anyone creating image sets for Q3/Wolf/etc does.
