I've read from the tutorial that it's possible to animate the sprite with a series of frames. On the tutorial it uses ent_create in creating the object..

action explosion()
{
my.ambient = 100;
my.flags |= BRIGHT;
while(1)
{
while (!key_e) wait (1);
for (my.frame=0; my.frame<12; my.frame += 3 * time_step) wait (1);
}
}

Is it possible to use pan_create for this instead of ent_create? what can we use instead of my.frame??

y u dont want to use ent_create ?

thats the way to do it easier. once u create the entity, u can assign the action to it.

and the sprites has animation frames with it. so we access each frame by my.frame here.

if u use pan_create only one bitmap/frame will be loaded.

I'm developing a pure 2d game, I use panels for all the contents.. it is specifically a ricochet (ball bouncing) like game but it's pure 2d.. all the balls, the catcher and bricks are wrap in panels..

I just want to make an animated explosive effect when the brick is broken..

ok. u can still use the ent_create for 2D animation. since sprite is 2D itself.

if u use panel, u will need to create the animation urself.

Thanks.. I just don't want to load any level to my game.
If I'll be going to use panels, how can I animate them? any clue?

ent_create doesnt load level. but yes u need load a level before using ent_create. u can use an empty level also.

as for animating panel, u need to play with the x, y, alpha values to create ur animation. u can look arnd on the forum, there have been demos of game using only panel including collision.

I've tried to use ent_create to have an explosion working with 11 frames tga file.
but now my problem is I can't change the x and y position of the explosion, it stays at 1 position where it originated.

I've tried to load level at main function and call ent_create at other function that traps the panel collisions but the position of the animated sprite doesn't change even if I'll feed variable x and y position to it..

ent_create("explo+11.tga", vector(xPos, yPos, 0), explosion);

where xPos and yPos is variable accroding the to position of the brick being broken..

when u create it, it is created at position (xPos,yPos,0), then even if the xPos and yPos values changes, it wont change. u need to change the value of the entity's position. see the example:




Now to move the sprite u need to modify the x and y of the entity and also other physical properties e.g:



This will animate the sprite in someway. u play around with the values and this should be fine.

#include <acknex.h>
#include <default.c>


void main()
{

fps_max = 40; // limit the frame rate to 40 fps
video_mode = 8; // run at 1024 x 768 pixels
video_depth = 32; // 32 bit mode
// video_screen = 1; // start in full screen mode
//level_load(NULL);
//wait(5);

}

ENTITY* sprite_anim;

sprite_anim = ent_create("explo+5.tga", vector(200, 200, 0), NULL);

action test()
{
sprite_anim.scale_x = -1;
}





function move_startup()
{
test();
}

what is wrong here???

plz help!

use ent_animate to animate the sprite...
