Spawn a ped
Spawning a ped (also called character or actor) is not as simple as inserting one line. There are steps that need to be taken in order to successfully spawn a ped. This tutorial will show you the basic steps of spawning a ped using a format used in Sanny Builder. These examples are for San Andreas but with minor tweaks can be used for GTA III and Vice City.
Create your thread
First, create a thread. Here is an example:
004F: create_thread @LoadModel
:LoadModel // add code from tutorial here 004E: end_thread
:LoadModel // add code from tutorial here end_thread
Request your model
It is very important to request the model of your ped. You can find a list of all peds available to use in the default.ide file for GTA III and Vice City or the peds.ide file for San Andreas. Use opcode 0247 or the command Model.Load to request your ped model. The script normally uses the ped's ID number but Sanny Builder support using the ped's model name with a hash character. Let's try the first ped in the list, BFORI.
0247: load_model #BFORI
There are some ped-spawning opcodes that do not need the ped's model to be loaded. See below for more information.
Check if the model is loaded
Next, you have to check if the model is loaded using an IF statement with the conditional opcode 0248 or the command Model.Available. If your create a ped with an unavailable model, the game will crash.
repeat wait 0 ms if 0248: model #BFORI available then break end until false
repeat wait 0 if Model.Available(#BFORI) then break end until false
Alternatively, this check can be bypassed entirely if opcode 038B is used after the models are requested, but the simplicity in coding requires trading off some hiccups to the game as the models are streamed.
Below you can find the code that the game uses to check if a model is loaded.
while 8248: not model #BFORI available wait 0 end
Create your ped
Now you can use the main opcode to create a ped: 009A, or the command Actor.Create. The opcode includes the ped's pedtype and the coordinate to spawn the ped. Sanny Builder has a built-in coordinates tool. Go to Tools>IDE Tools>Coords manager... or use the shortcut Ctrl+Alt+1 while the game is running. This will show the current position of your player character.
009A: 0@ = create_actor_pedtype 4 model #BFORI at 0.0 0.0 0.0
Actor.Create(0@, 4, #BFORI, 0.0, 0.0, 0.0)
There are other opcodes that also spawn a ped in different situations, including:
There are opcodes that can spawn a random ped without the need to request the model of the ped.
|0376: Creates a random ped.|
|0560: Creates a random ped as a driver in a vehicle.|
|0561: Creates a random ped as a passenger in a vehicle.|
Some pedtypes are limited to be compatible to specific models or else the game may crash.
- Pedtype 6 can only be used with models between 0 and 4 (#null, #cop, #swat, #fbi, #army).
- Pedtype 16 can only be used with model 5 (#medic).
- Pedtype 17 can only be used with model 6 (#fireman).
Release your model
After the ped is created and the model is no longer needed, release it using opcode 0249 or the command Model.Destroy
0249: release_model #BFORI
Set your ped
You can now add settings and attributes to your ped, like rotating your ped or adding animations to your ped. The variable 0@ is the handle of your ped, like an identifier. Use this variable when using opcodes specific to your ped. You can search these opcodes by using Sanny Builder's Opcode Search Tool. Go to Tools>IDE Tools>Opcode Search... or use the shortcut Ctrl+Alt+2. Then type actor in the search box to find a list of named opcodes related to it.
// load model, required to prevent unnecessary crash! 0247: request_model #BFORI // check if model is loaded repeat wait 0 if 0248: model #BFORI available then break end until false // spawn character 009A: 0@ = create_actor 4 #BFORI at 0.0 0.0 0.0 // cleanup 0249: release_model #BFORI
