Hi i'm new on GameGuru, i want to know how i can make a text "PRESS E TO INTERACT or something like that" on a Model and after the player press it, the model disappear, how i can do something like that? Can you help me please?

I make the text, now i have to understand how to make the model disappear when press "E" and how to make another model spawn in the same place... i'm starting with that

if GetScancode() == 18
Spawn Soldier

I have the code for your reference
using UnityEngine;
using UnityEngine.UI;

public class InteractableObject : MonoBehaviour
{
public Text interactText; // Assign the UI Text element in the Inspector

void Start()
{
interactText.gameObject.SetActive(false); // Hide the text initially
}

void Update()
{
if (Input.GetKeyDown(KeyCode.E))
{
RaycastHit hit;
if (Physics.Raycast(Camera.main.transform.position, Camera.main.transform.forward, out hit, 5f))
{
if (hit.transform == transform)
{
interactText.gameObject.SetActive(false); // Hide text after interaction
gameObject.SetActive(false); // Hide the model
}
}
}
}

void OnTriggerEnter(Collider other)
{
if (other.CompareTag("Player"))
{
interactText.gameObject.SetActive(true); // Show the text when the player is near
}
}

void OnTriggerExit(Collider other)
{
if (other.CompareTag("Player"))
{
interactText.gameObject.SetActive(false); // Hide the text when the player leaves
}
}
}

To create an interactive model in a game where a text like "PRESS E TO INTERACT" appears, and upon pressing the key the model disappears, you can use a game development platform like Unity or Unreal Engine.

@Matteo99x and all,

The programming code used in game engines such as Unity (C#, JavaScript or Boo programming, depending on the year of the version you are using) or Unreal Engine (basically, it uses C++ programming).

However, GameGuru Classic Engine uses Lua script programming. Therefore, I'm sorry to say, but the examples of scripts written for Unity or Unreal Engine, shown above, will not work at all in GameGuru Classic for what you want to do.

To do what you want, it is not a very easy task for someone who is just starting with GameGuru Classic programming, especially spawning a new object in the same place, where another one disappeared.

To make any object disappear or appear is relatively easy, see the example below :

function hidemyobj_init(e)

Show(e);

end -- Do not remove it

function hidemyobj_main(e)

e_Key = g_Scancode;

-- e_Key for E key = 18; therefore:

if e_Key==18 then
Hide(e);
end

-- To show up the object again, click on Y key = 21; therefore

if e_Key==21 then
Show(e);
end


end -- Do not remove it

Now, save the script above with the name hidemyobj.lua in the GameGuru Classic scriptbank directory (folder). Run GameGuru Classic, and click on add new entity icon.

In Barrels, click on Barrel (Clean) and then on OK.

Place it somewhere in the terrain. Left-click on the barrel (clean) and then on properties. In the AI ​​System Main field.

A small rectangle or square with three dots will appear.

Click on the small square mentioned, and look for the script above, called hidemyobj.lua.

Then, click on the Apply Changes button. After returning to the terrain editor, click on the Player Start icon and place it near the barrel.

So, click on the button with a rocket (Test Game) in the icon bar and test the Lua script above.

A final reminder: the name of a script in GameGuru Classic is always lowercase, remember that.

That's all.
Cheers,
-Northern

What I do is whenever the character moves or the camera rotates, I do a raycast from the camera and check if I hit anything. If it hits an object I check if it implements my InteractableInterface and if so I display the message in the UI. If it hits nothing then I clear the message and clean up.
