Hi guys
i want to make plasma sprites.For example i will show this picture

How can i make it in firerocket to use for example this jpg file?I tried fimg but it wrote me that save function does not work.Is there some way to create more frames for example on missile explode?

PS:Sorry for my english.

You need to use the alpha channel of the TGA to represent transparency.

PLease can you send me some freeware program which will do this?I think that Photoshop can do that but it is shareware.

I think http://www.gimp.org/ is probably the best freeware image manipulation software., but I'm not sure since I use a commercial package.

you have to manually loop it.

go through each frame. it won't play on it's own.

Do you mean on qc or in fimg?

He means in qc.

[metlslime]

there is client-side looping on sprites (framegroups) just like in models. Not sure what sprite tools support it though.

....or engines.

I know Qtest supported that feature

[lukas2288]

i know that here is some example code in weapons qc:
void() s_explode1 = [0, s_explode2] {};
void() s_explode2 = [1, s_explode3] {};
void() s_explode3 = [2, s_explode4] {};
void() s_explode4 = [3, s_explode5] {};
void() s_explode5 = [4, s_explode6] {};
void() s_explode6 = [5, SUB_Remove] {};

void() BecomeExplosion =
{
self.movetype = MOVETYPE_NONE;
self.velocity = '0 0 0';
self.touch = SUB_Null;
setmodel (self, "progs/s_explod.spr");
self.solid = SOLID_NOT;
s_explode1 ();
};


so here is the new effect spr:

void() n_effect1 = [0, n_effect] {};
void() n_effect2 = [1, n_effect] {};
void() n_effect3 = [2, n_effect] {};
void() n_effect4 = [3, n_effect1] {};

void() NewEffect =
{
self.movetype = MOVETYPE_NONE;
self.velocity = '0 0 0';
self.touch = SUB_Null;
setmodel (self, "progs/neweffect.spr");
self.solid = SOLID_NOT;
n_effect1 ();
};


But how can i put it for example in FireRocket function to replace missile.mdl with animated NewEffect?

If this is an impact explosion, then just look in T_MissileTouch and replace the BecomeExplosion(); with NewEffect();. (note that you have a bug in your animation code that will cause the animation to never dissappear and continue to animate.)

If this is for a projectile animation, then what you need to do is add something like this:

Code: Select all

void() PlasmaThink =
{
  self.frame = self.frame + 1; // Advance frame by one every think.

  if(self.frame > 3)  // start from beginning of animation if it's time
   self.frame = 0;

  if(self.attack_finished <= time) // Remove if lifetime is exceeded
   remove(self);

  self.think = PlasmaThink;
  self.nextthink = time + 0.01; // this is the anim framerate speed
};


Then, in FireRocket or whatever change this:

Code: Select all

missile.nextthink = time + 5;
missile.think = SUB_Remove;

setmodel(missile, "progs/missile.mdl");


To this:

Code: Select all

missile.frame = 0; // set what frame it starts at
missile.nextthink = time + 0.01; // set nextthink time
missile.think = PlasmaThink; // set what it's supposed to think about
missile.attack_finished = time + 5; // dissappear in 5 secs if no impact

setmodel(missile, "progs/neweffect.spr"); // set model to new plasma sprite

Well, glquake broke a bunch of stuff with sprites (e.g. orientations) and models (i.e. only correctly supports 2- or 4- frame skingroups) so it could have broken sprite framegroups too. And since glquake is the daddy of a bunch of engines out there, if glquake broke it, it's likely broken in a bunch of engines.
