Minimap mod

[DoctorGester]

Hi there. There's my mod, adding minimap to game interface. It's poorly done, because i have some problems with coding.

Problem 1:
Mini map shows only units, not obstacles. I think at the moment there's no way to get shapes of obstacles on the level.

Problem 2:
I couldn't find the function, which returns current facing of unit. Insted of it i'm using velocity of unit, that sometimes looks weird on the minimap.

Problem 3:
I couldn't find the way to move minimap to the corner of screen, or the function, returning screen size. So minimap is placed near the center of screen.

Mod installation:
1. Place minimap.html to Overgrowth\Data\UI\dialogs
2. Replace Overgrowth\Data\Scripts\level.as with my level.as or use instruction below to modify it.
3. ??????

If you want to modify level.as by yourself follow these steps:
1. Place

Code: Select all

uint32 minimap = 0;
bool mapPreload = true;

at the first line.
2. Place

Code: Select all

    if ((has_gui && minimap != 0) || GetPlayerCharacterID() == -1){
		gui.RemoveGUI(minimap);
		minimap = 0;
	} else if (!has_gui && minimap == 0 && GetPlayerCharacterID() != -1){
		minimap = gui.AddGUI("minimap","dialogs\\minimap.html",600,400);
		if (mapPreload){
			gui.RemoveGUI(minimap);
			minimap = gui.AddGUI("minimap","dialogs\\minimap.html",600,400);
			mapPreload = false;
		}
	}
    UpdateMap();

after

Code: Select all

void Update() {
    gui.Update();

3. Place

Code: Select all

void UpdateMap(){
	int player_id = GetPlayerCharacterID();
    if(minimap == 0 || player_id == -1){
        return;
    }
	MovementObject@ player_char = ReadCharacter(player_id);
	float x = player_char.position.x,
		  y = player_char.position.z;
    int num = GetNumCharacters();
	for(int i=0; i<num; i++){
        MovementObject@ char = ReadCharacter(i);
		float cx = char.position.x,
			  cy = char.position.z;
		float vx = cx - x,
			  vy = cy - y;
		float dist = sqrt(vx * vx + vy * vy);
		int state = 0;
		if (char.controlled)
			state = 1;
		if (char.IsKnockedOut() != _awake)
			state = 2;
		vx += 50.0f;
		vy += 50.0f;
		vx *= 2.0f;
		vy *= 2.0f;
		vec3 vel = char.velocity;
		float an = atan2(vel.z, vel.x);
		gui.CallFunction(minimap, "addObject(" + vx + "," + vy + "," + an + "," + state + ")");
    }
	gui.CallFunction(minimap, "draw();");
}

before

Code: Select all

const float _reset_delay = 4.0f;
float reset_timer = _reset_delay;

5. PROFIT AGAIN

this is so far beyond my understanding of scripting i can't even comprehend it, cool mod.

Hmm, that's pretty cool. Can you take a screenshot via the AS? You could take a screenshot from up above and save it as a texture, or maybe make the minimap a small game screen itself that looks down upon the player from the sky. Might solve issues with shapes and things, although I'm not sure if that's what you're wanting.

> Can you take a screenshot via the AS
i think no =(

Wow, this is an awesome use of scripting! Maybe as a next step we can have someone generate overhead images for each map.

I tried to solve problem #2 with the following code:

Code: Select all

vec3 facing = char.GetFacing();
float an = atan2(facing.z, facing.x);

though strangely enough the game responds with the message "No matching signatures to 'MovementOject::GetFacing()'", which is odd, as the function is used in aschar.as (on line 781, for example). If anyone has any idea why, I'd love to know!

Also, I decided to take a screenshot so that people could get an idea of what it looks like (click to enlarge):

Samusaaron3, thanks. i tried to use GetFacing too, but i was getting same error as you.

[AAorris]

The problem you guys are having with GetFacing is because level.as does not have access to that function in movement_object defined in player_dump.as... the only scripts that can access it are mentioned by learn_more:

* Files that can access these (and included) functions/objects/properties:
*/

// Data/Scripts/enemycontrol.as
// Data/Scripts/aschar.as
// Data/Scripts/interpdirection.as
// Data/Scripts/aircontrols.as
// Data/Scripts/fliproll.as
// Data/Scripts/ledgegrab.as
// Data/Scripts/playercontrol.as

I'll investigate further about accessing them now :3
