@Ulysse Martin (youle): Is this code needed for blenderplayer too ?

@Porteries Tristan (panzergame): I guess yes.

(Parenthesis: I didn't even compiled the blenderplayer because my goal was not to restore completely the old game engine.

I just wanted:

1. point the things that will cause problems if/when we'll merge upbge.
2. Have a reference commit to make bisect easier.

The point 2) is the most important to me because when you make bisect you have to know the moment where a thing was working or not. So for many things, this commit will be the "git bisect good" reference. If something is broken again, we will know that at this moment it was good.

BUT: If you want to add more code and restore more things, try to make blenderplayer work etc, I also agree if you want.)

/* temporary hacky solution waiting for CoW depsgraph implementation */
#define DEG_OBJECT_ITER(sl_, instance_) \
{ \
/* flush all the depsgraph data to objects */ \
Object *instance_; \
Base *base_; \
for (base_ = (sl_)->object_bases.first; base_; base_ = base_->next) { \

	    if ((base_->flag & BASE_VISIBLED) != 0) {                             \
	        instance_ = base_->object;                                        \
	        instance_->base_flag = base_->flag;                               \
	        instance_->base_collection_properties = base_->collection_properties;

#define DEG_OBJECT_ITER_END

It's temporary solution. In upbge we BL_KetsjiEmbedStart almost doesn't exist anymore anyway... If I remove this code, physics doesn't work anymore.

Nevermind, I'll read your today's commit and try to understand what I need to change.
