That would be an example for a higher jump

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if(newkeys & KEY_JUMP) {
        new
            Float: vX,
            Float: vY,
            Float: vZ;
        GetPlayerVelocity(playerid, vX, vY, vZ);
        SetPlayerVelocity(playerid, vX, vY, (vZ * 1.3));
    }
    return 1;
}

Just look at the code and make it for running (you could use KEY_SPRINT for that)
