I guess the wall can be detected with ColAndreas. Set a point to somewhere in front of the player and see if there's an object between it:

Function from AbyssMorgan's 3DTryg:

PHP код:

Tryg3DProt:: bool:IsBetweenPlayerToPointIsWall(playerid,Float:x,Float:y,Float:z) {
    new Float:xA,Float:yA,Float:zA,Float:xC,Float:yC,Float:zC;
    GetPlayerPos(playerid,xA,yA,zA);
    CA_RayCastLine(xA,yA,zA,x,y,z,xC,yC,zC);
    if(xC == 0.0 || yC == 0.0 || zC == 0.0) return false;
    return true;
} 


@Crayder, any better ideas? (I linked this post on his VMs)
