What is game_ui good for ?
Its a very nifty entity that lets you take the player input, say WASD and attack buttons plus more, and convert them into stuff happening ingame.
Like Press forward and a thruster activates, back and it deactivates.
How to create vehicles and other user operated objects
Its simple to use:
Step 1: Create a func_Button
Step 2: Set the flags
- Don't move
- Toggle
- Use Activates
Step 3: Set "Delay before reset" in the properties to 0
Step 4: Create two env_sprites, to indicate if the game_ui is active or not
- Use these two sprites:
- materials/Sprites/greenglow1.vmt
- materials/Sprites/redglow1.vmt
- The sprite with the redglow should have the flag "Start on" checked
- Name both sprites "sprite"
Ok, here comes the glory of it all:
Step 5: Make a game_ui entity and name it game_ui
Step 6: Goto the output tab and make these outputs:
This will toggle the two sprites whenever you enter or exit the game_ui, Enter = Red off, Green on. vice versa
Step 7: Go back to the Buttons output tab and make these two outputs:
That means when you press the button activate the game_ui, and when you press it again deactivate game_ui
Which will then turn on/off the sprites...
Its now ready for your input...
Step 8: In the Game_ui output tab you have these options (and some more not discussed in this tutorial as of yet)
- PlayerOn: Triggers when the player enters the game_ui
- PlayerOff: opposite of PlayerOn
- PressedAttack: Primary Attack
- PressedAttack2: Secondary Attack
- PressedBack: Equals S if u have defualt settings
- PressedForward: Equals W if u have defualt settings
- PressedMoveLeft: Equals A if u have defualt settings
- PressedMoveRight: Equals D if u have defualt settings
