The Yes Steve Model mod also provides a number of commands. Most of these commands require permission level 2 to execute.

All commands have in-game hints. All model IDs and player IDs are intelligently suggested.

Main Commands

These commands can be executed on both the server and the client.

• /ysm model reload Reload all model files: Also synchronizes the model files to all client players.
• /ysm model set <player> <model_id> <texture_id> [ignore_auth] Assign a specific model and texture to a player. The last ignore_auth parameter is optional. When set to true, it will ignore the model authorization and force the model to be assigned to the player.
• /ysm play <player> <animation_name> Force a player to play an animation.
• /ysm play <player> stop Clear the animation that was previously forced to be played by the player.
• /ysm auth <player> all Authorize all models to a player.

• /ysm export <model_id> [extra_info] Export a model to the YSM exclusive model format. You can also add additional information.
• /ysm ping Test the connectivity between the client and the server. If the message "The server mod and the client version are inconsistent" appears, you can execute this command. This command has no permission requirements.
• /ysm molang execute <player> <expr> Execute molang on a specified player. It can be used in multiplayer games, but the execution result will not be printed.
• /ysm model disable <player> [true | false] This command was added in version 2.5.2 and is used to disable a player's model. When set to true, the corresponding player will no longer display the YSM model and will revert to the original model.
