Description​

Sets the velocity of an NPC.

NameDescription
npcidThe ID of the NPC
Float:xThe X velocity component
Float:yThe Y velocity component
Float:zThe Z velocity component

Returns​

Returns true on success, false on failure.

Examples​

public OnPlayerCommandText(playerid, cmdtext[])
{
    if (!strcmp(cmdtext, "/setvelocity ", true, 13))
    {
        new npcid = PlayerNPC[playerid];
        if (npcid == INVALID_NPC_ID)
            return SendClientMessage(playerid, 0xFF0000FF, "You are not debugging a NPC.");

        if (!NPC_IsValid(npcid))
            return SendClientMessage(playerid, 0xFF0000FF, "Invalid NPC.");

        new Float:x, Float:y, Float:z;
        new idx = 13;

        // Parse x
        while (cmdtext[idx] == ' ') idx++;
        new startIdx = idx;
        while (cmdtext[idx] != ' ' && cmdtext[idx] != '\0') idx++;
        new xStr[32];
        strmid(xStr, cmdtext, startIdx, idx);
        x = floatstr(xStr);

        // Parse y
        while (cmdtext[idx] == ' ') idx++;
        startIdx = idx;
        while (cmdtext[idx] != ' ' && cmdtext[idx] != '\0') idx++;
        new yStr[32];
        strmid(yStr, cmdtext, startIdx, idx);
        y = floatstr(yStr);

        // Parse z
        while (cmdtext[idx] == ' ') idx++;
        z = floatstr(cmdtext[idx]);

        NPC_SetVelocity(npcid, x, y, z);
        SendClientMessage(playerid, 0x00FF00FF, "NPC %d velocity set to %.2f, %.2f, %.2f", npcid, x, y, z);

        return 1;
    }
    return 0;
}

Notes​

  • Velocity values determine the speed and direction of movement
  • Positive Z values move the NPC upward, negative values move downward
  • This can be used to create custom movement behaviors
