Angles - GoldenLion - 01.09.2016

Hi, how would it be possible to get a player's and target's angle and check if player is in front of target or player is behind the target? I want to apply different animations when player gets shot either in back or front but I can't understand how to do it.

like that: https://gyazo.com/94ce8d9cd3503172a1889147d65cbef6

GetPlayerFacingAngle and using trigonometry... You know, that thing that you didn't learn, in those classes because you thought it wasn't "needed". xD

Re: Angles - GoldenLion - 01.09.2016

no i was never learning that i think and my mind blowns up when i think about it, i kinda know how to do it but i don't at the same time lmao

I got told in school I'd only ever pass English, but in the end failed English, passed Maths and Science, and most of my class time in both of those classes was sleeping in the back of the class.

lol ok, but do u know how to make it? anyone?

PHP код:
new Float:x,Float:y,Float:z,
    Float:tx,Float:ty,Float:tz,
    Float:rx,Float:rz,Float:offset_rz;
GetPlayerPos(center_playerid,x,y,z);
GetPlayerFacingAngle(center_playerid,offset_rz);
GetPlayerPos(circle_playerid,tx,ty,tz);
GetRotationFor2Point3D(x,y,z,tx,ty,tz,rx,rz);
CompRotationFloat(rz-offset_rz,rz);
//compare rz

Re: Angles - GoldenLion - 01.09.2016

Erm, would it be possible without any additional includes?

Uh, yea, also could you give an example with OnPlayerGiveDamage? I don't really understand this thing. If It's the only way to do it then I will use it. Will I need any plugins?

Re: Angles - Sew_Sumi - 01.09.2016

In the thread it says it only needs the plugins for the more advanced portions. Check that thread, it seems like it shouldn't need anything extra.

PHP код:
GetRotationFor2Point3D(x,y,z,tx,ty,tz,rx,rz); 
CompRotationFloat(rz-offset_rz,rz); 
Those are the 2 functions that the include is needed for. They don't seem like they are under the plugin required listings.

Re: Angles - AbyssMorgan - 01.09.2016

3DTryg. It does not require plug-ins.

PHP код:
public OnPlayerGiveDamage(playerid, damagedid, Float:amount, weaponid, bodypart){
    if(damagedid != INVALID_PLAYER_ID){
        new Float:x,Float:y,Float:z, 
            Float:tx,Float:ty,Float:tz, 
            Float:rx,Float:rz,Float:offset_rz; 
        GetPlayerPos(damagedid,x,y,z); 
        GetPlayerFacingAngle(damagedid,offset_rz); 
        GetPlayerPos(playerid,tx,ty,tz); 
        GetRotationFor2Point3D(x,y,z,tx,ty,tz,rx,rz); 
        CompRotationFloat(rz-offset_rz,rz); 
        //compare rz
        if((rz >= 0.0 && rz <= 45.0) || (rz >= 315.0 && rz <= 360.0)){
            //front of skin
            
        } else if(rz >= 45.0 && rz <= 135.0){
            //right of skin
            
        } else if(rz >= 135.0 && rz <= 225.0){
            //back of skin
        } else if(rz >= 225.0 && rz <= 315.0){
            //left of skin
            
        }
    }
    
    return 1;
}
