示例1: updateParticleShapeTransforms
import processing.core.PShape; //导入方法依赖的package包/类
@Deprecated
static final public void updateParticleShapeTransforms(World world, PShape group_particles, boolean rotate){
int shp_count = group_particles.getChildCount();
if(shp_count == 0){
return;
}
PShape[] shp_particles = group_particles.getChildren();
int count = world.getParticleCount();
if (count == 0) return;
if( count != shp_count ){
System.out.println("ERROR: Box2dUtils.updateParticleShapeTransforms: particles numbers dont match "+count+" != "+shp_count);
count = Math.min(count, shp_count);
}
Vec2[] pos = world.getParticlePositionBuffer();
Vec2[] vel = world.getParticleVelocityBuffer();
if(rotate){
for (int i = 0; i < count; i++) {
shp_particles[i].resetMatrix();

for (int i = 0; i < count; i++) {

示例2: updateParticleShapeBuffer
import processing.core.PShape; //导入方法依赖的package包/类
@Deprecated
static final public int updateParticleShapeBuffer(World world, PShape group_particles){
int particle_num_old = world.getParticleCount();
int particle_num_new = 0;
if(particle_num_old == 0){
return 0;
}
if(group_particles.getChildCount() == 0){

}
// The following is way faster, then removing shapes in place.
// ... even when iterating backwards, a lot of repeated/unnecessary copying
// will be needed.
PShape group = group_particles;
PShape[] shapes = group.getChildren();
int[] particle_flag = world.getParticleFlagsBuffer();
// re-map particles, so that zombies are left out
for(int i = 0; i < particle_num_old; i++){
if((particle_flag[i] & ParticleType.b2_zombieParticle) == 0){
shapes[particle_num_new++] = shapes[i];
}
}
// remove number of zombies by triming the buffer to the new size
// unfortunately PShape offers no better way to do this
for(int i = particle_num_old - 1; i >= particle_num_new; i--){
group.removeChild(i);
}
int removed = particle_num_old - particle_num_new;
return removed;
}
示例3: removeChilds
import processing.core.PShape; //导入方法依赖的package包/类
private void removeChilds(PShape shp){
if(shp == null){
return;
}
int num_childs = shp.getChildCount();

}
int num_childs = shp.getChildCount();
