OK like the Header says, i want to know, ( and maybe this is a Question best suited for Amenmoses. ) if the player has an axe in his hand and just hit in the air there is no collision correct.? Ok so if you hit and drum with the same axe then GG knows there is collision because you see the steel sparks when you hit the drum, so now we go one step further if you hit ( chop) a piece of wood or lets say a tree then the GG engine also know there was an collision because you then see wood splinters, That means that the Engine knows what kind of material you are hitting because of the wood or steel sparks. .. Ok by keeping that in mind is it then not possible to have a wood chopping script that determents weather the player are chopping a tree / wood with out putting a script on every single tree in the game.??

If this is possible then it would make it so much easier to have a survival game were one has to chop trees without having to put a script on every single tree in your game that you would like to be chopped.

Ok so if you 'chop' a static entity then the engine will create the effect of the 'chop' depending on the 'material' of that entity.

But there is no engine behaviour built in to do anything else, the only way of getting any extra functionality is to make that entity dynamic and attach a script.

But if the engine knows what kind of material is being hit , is there then not a way then to attach a script to an always active entity that can monitor the collision type and then transport it to a workable value.?

True, hundreds of trees each with a script can kill fps. But I'm guessing there's just not a Global.lua script function to call that value of current hit material? That is certainly in the engine somewhere, but might require a request @ Github for Lee to supply access to the data.

Seems putting a script on an object that registers the health of it might be your closest access right now- and besides you must destroy the object being hit eventually- right- or you could get 245 semi-truck loads of lumber out of one small tree. Even better than Fortnite!

I did this [LONG time ago] to mimic destroy obstacles (fall trees for example). So easy enough. Maybe you could also blow up stacks of lumber with dynamite for extra points? So standing near a tree (PlayerDistance) and health drops (GetEntityHealth) Try it first and see how it goes.

if the axe is an actual weapon used by the player you want the GetBullethit() function
i.e. local bx, by, bz, m, t = GetBulletHit()
bx,by,bz = the location
m = the material
t = not sure
m will return a number which relates to the index of the material, not all objects will be set correctly but you can prompt it out to see the results as you hit stuff.

Yes GetBulletHit() will tell you the location of a hit and any material that has been defined, my bullet holes script uses it, but that doesn't really help as you would still need to figure out what entity is being hit somehow.

i.e. just because the material is 'wood' doesn't mean you have hit a tree!

I suppose you could ray cast around at the hit point and figure out which object is likely being hit and then look to see if that object relates to an entity in g_Entity list then get the name of the entity and process that to see if it might be a tree (although there is no defined standard for naming so it might be "Red Oak" for example).

As long as you plan everything out in advance you could do it that way.

@PCS--
Are you kidding!? RTX 3060 12GB GDDR6?! Just noticed- cool.

I just wrote an script w/ player distance and Entity health checks.
Works a treat. One single script on a clean, blue barrel, (rudimentary - no tree falling yet.)

80 trees (for do loop- which usually never significantly effects fps up to 100+)
You could probably have 3060 on your system!

so no frames dropped -- must consider that I am using boxes to test it with,
on an otherwise empty map. Also currently no material detection... possible to add.
Entities must be dynamic which I would imagine would be the case on any
way you try it. ( to get [e]-data )

Well, I will try putting trees down to test on another map. Let's go ye ol GG!

BTW, I see no reason why trees cannot be recycled. Maybe you would only need ~50?

yes i got the RTX 3060 for my birthday, so now I'm full on testing Max. hehehe

This card makes a huge difference on a lot of games.
I have been saving for this a long time.

t = third person character entity Id (not sure why I added that tbh, so long ago I can't remember)

Wonder...
How to make any object a weapon?
If say for an example just for giggles I wanted to change a pillow into a weapon,
more than just an .fpe setting? Which script to use, and can extra behavior be
added by modifying said script - as it remains a weapon? Thoughts?

if you mean a weapon that uses the GG system you need to create a gunspec file for it and set it up like the other weapons
