The Z position of the object doesn't change - It slides to its end position in mid-air: http://i.imgur.com/HHUBROq.png
I understand that collisions with the projectile and the CA map are done internally, right? Objects don't simulate collisions yet?

I tested the example and my objects are staying at ground after collision.

There's no collisions with projectiles, so if you throw a deagle and another deagle at the same time from opposite direction, they won't collide but go straight to their respective path. (and all these checks are done internally you just need to throw the deagle!)

What i can think of in your case might be player collision which might bug, did you throw the object very close to a wall?

Edit: or maybe you have a big "sphere_radius" set in Projectile function?

I threw the deagle right in front of Jefferson motel in the middle of the street, so I guess not. To further test this, I drove to LV to test it in the middle of nowhere and same results - it just slides to its destination in mid-air.

And I meant collisions with walls and such, because that isn't working either.

EDIT: I took the example from your GitHub and didn't change anything. The code is loaded in as a filterscript.

Cause that can be the only reason why collisions are not working, due to unsuccessful loading of collision data.

Try it in a gamemode, edit "OnFilterScriptInit" to "main".

Nice include, very easy to use.

Update v1.3.3:
- Gravity effect introduced (action = reaction), this was responsible for no bouncing before.
- Modified default param values in "Projectile" so the setting is now set for a ball like object nature.

Known bug:
- Sometimes the object goes under footpaths while sliding which cause the object to float and it never calls OnProjectileStop.

Nice! Though, OnProjectileStop seems to be called prematurely. It's an annoyance when you create an object that is supposed to replace the projectile under OnProjectileStop (the replacement object would be in the air instead of on the ground).

I took your example and just added the CreateObject line under OnProjectileStop because that's what roughly happens in my script:

PHP Code:



#include <a_samp>

#include <zcmd>

#include <projectile>


new iProjObject[MAX_PROJECTILES];


public OnFilterScriptInit()

{

    CA_Init();

    return 1;

}


CMD:test(playerid)

{

    new Float:x, Float:y, Float:z, Float:ang;

    GetPlayerPos(playerid, x, y, z);

    GetPlayerFacingAngle(playerid, ang);


    new i = Projectile(x, y - 0.5 * floatcos(-(ang + 90.0), degrees), z, 2.0 * floatsin(-ang, degrees), 2.0 * floatcos(-ang, degrees), 4.0, .collision_friction = 5.0, .sphere_radius = 0.01, .gravity = 13.0);

    if (i == -1)

        return 0;

    DestroyObject(iProjObject[i]);

    iProjObject[i] = CreateObject(348, x, y - 0.5 * floatcos(-(ang + 90.0), degrees), z, 93.7, 120.0, ang + 60.0);

    

    ApplyAnimation(playerid,"GRENADE","WEAPON_throwu",3.0,0,0,0,0,0);

    return 1;

}


public OnProjectileUpdate(projid)

{

    new Float:x, Float:y, Float:z;

    GetProjectilePos(projid, x, y, z);

    SetObjectPos(iProjObject[projid], x, y, z);

    return 1;

}


public OnProjectileStop(projid)

{

    new Float:x, Float:y, Float:z;

    GetProjectilePos(projid, x, y, z);

    CreateObject(348, x, y, z, 90.0, 0.0, 0.0);

    return 1;

}

Update v1.3.4:
- Fixed sphere hanging in space when colliding with a player.
- Fixed min and max height calculation.

@Andy: This version should get rid of all those issues you addressed before. Give it a try!

Yep, thank you

Re: projectile.inc - PeppeAC's physics modified and simpler version - Gammix - 09.04.2017

Update v1.3.5:
- Fixed projectile index management, poolsize method used.
- New functions:

PHP Code:



IsValidProjectile(projid);

GetProjectilePoolSize();

- Callback "OnProjectileCollide" has a param change, the "modelid" now is "extraid". Read the main post for info. about it.

PHP Code:



OnProjectileCollide(projid, type, Float:x, Float:y, Float:z, extraid);

- New example of "Grenade launcher" has been added.

Great! Have your rep.

Why does an object fall under the ground?

Definitely this could be the reason:

Nice work!

Re: projectile.inc - PeppeAC's physics modified and simpler version - Riddick94 - 22.10.2018

Why did you rename "StopProjectile()" to "DestroyProjectile()" while it doesn't make much sense? I had to edit include to get my things to work.
