Umm... good luck. There's a lot of code required for doing this right that just isn't publicly exposed in the API yet. Calling onObjectHit is okay, but without more direct access to the underlying collision code, I'd honestly be tempted to spawn a bunch of invisible PLAYERBULLET objects in a circle around the explosion and give them .animSpeed values based on their distance from the center. For extra credit, you could also search through the object list, decide which ones are near enough, and if they have .isBlastable set to true, change their .xSpeed and .ySpeed values.

But I want a pickup with its own sprite

For most cases, just calling determineCurAnim should be fine?

urge to simplify rising
Code:
if (obj.ySpeed == 0) {
int frame = obj.objectID * 8 + jjGameTicks;
if (obj.yPos > jjWaterLevel) frame = frame*2 + (int(obj.xPos) + int(obj.yPos) * 256)*16;
else frame = (frame + int(obj.xPos) + int(obj.yPos) * 256)*16;
jjDrawSpriteFromCurFrame(obj.xPos, obj.yPos + jjSin(frame)*4, obj.curFrame, obj.direction);
}
else obj.draw();
