Sprite collision revisited

[spenoza]

So, here's how Mike Daily handles collisions. He uses Gamemaker as a starting point because he argues it does things horribly. How does his method compare to your own?

I have already red this ..

Personaly i'am using bouding box, this methos is IMO the more simpliest,and give very good results in most cases.
I have also used hardware sprite detection + bouding boxes on pce.

Pixel perfect is the best, but also more CPU consuming,and difficult to implement.

the hardware collision isn't so great if the sprites aren't taking up the whole box lol.


I use bounding boxes too, as it makes the most sense and offers great flexibility.

Yes but you lunch a bounding test ONLY when an hardware collide interrupt is set ..
you avoids more collisions tests for nothing  .

But i admit for PCE this is very very limited .

I suppose you could do that, but is the gain really worth a damn?

i don't know really, i think so, and i confirm if you're using HuC for testing .
Because you probably use arrays for sprites coordinates.

This method is only usefull if sprite 0 is assigned (for exemple), for player shoot,and can shoot one at the same time  ..

I don't use arrays, period.

Separates variables ??, or the use of spr_get ???

[Arkhan Asylum]

Neither.

Lol,stack ???
printer??
3D storage ???
Aliens system ???
