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.
|
||||
|
||||
ToDo
|
||||
====
|
||||
|
||||
* make sprites always face the camera (is this done in camwindow.cpp ?)
|
||||
|
||||
* maybe add an option to scale the sprites in the prefs ?
|
||||
|
||||
* un-hack the default fall-though to "sprite" model version (see m_version)
|
||||
|
||||
* 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
|
||||
|
||||
* allow an entity to have both an .md? and a sprite model.
