This is the first time I use CodeAnalyst, I guess this is what we need.
This one is for the SFML code:
CS:EIP Symbol + Offset Timer samples
0xd33560 Particle::show 73.98
0xd31a70 Player::show_particles 13.12
0xd36150 std::_Remove_if<Particle *,bool (__cdecl*)(Particle)> 9.28
0xd37290 std::_Uninit_copy<Particle *,Particle *,std::allocator<Particle> > 0.9
0xd32800 World::show_stars 0.68
0xd36ed0 std::_Find_if<Star *,bool (__cdecl*)(Star)> 0.68
0xd363c0 std::_Remove_if<Star *,bool (__cdecl*)(Star)> 0.45
0xd32630 World::show_enemies 0.23
0xd32790 dead_s 0.23
0xd33410 Star::show 0.23
0xd34d60 main 0.23
11 functions, 82 instructions, Total: 442 samples, 100.00% of shown samples, 2.27% of total session samples
So the way I tested performance, since in this early version of my game there aren't many objects, I increased the particles coming out from the player's thruster (in both SDL and SFML, the same number)
In the SFML one it seems like this takes up everything.
Here is the code for Particle::show:
void Particle::show()
{
//Show image
if (initialized == false){
if (type == 1) part = p1;
else if (type == 2) part = p2;
else if (type == 3) part = p3;
else if (type == 4) part = p4;
else if (type == 5) part = bparticle;
else if (type == 6){
if ((rand() % 4) == 0)
part = p1;
else if ((rand() % 4) == 1)
part = p2;
else if ((rand() % 4) == 2)
part = p3;
else if ((rand() % 4) == 1)
part = p4;}
initialized = true;
}
if(alive)
{
part.SetPosition(x,y);
App.Draw(part);
//apply_surface( x, y, part, screen );
}
//Animate
//stuff here is not relevant, and its exactly the same in both
EDIT:
Since then I tested it with part.SetPosition(x,y); and App.Draw(part); commented out, so they are not drawn, and still Particle::show takes up 61% of the resources (was 74 previously)... with that commented out, the SDL and SFML Particle::show() are identical, except in SDL they actually get drawn.
I'll put the same code here for SDL for comparison, so you won't have to scroll back and forth.
void Particle::show()
{
//Show image
if (part == NULL){
if (type == 1) part = p1;
else if (type == 2) part = p2;
else if (type == 3) part = p3;
else if (type == 4) part = p4;
else if (type == 5) part = bparticle;
else if (type == 6){
if ((rand() % 4) == 0)
part = p1;
else if ((rand() % 4) == 1)
part = p2;
else if ((rand() % 4) == 2)
part = p3;
else if ((rand() % 4) == 1)
part = p4;}
}
if(alive)
apply_surface( x, y, part, screen );
//Animate
And CodeAnalyst result for the SDL code, Particle::show doesn't strain it as much at all
