Player follows mouse

[steptoe]

Hi

I am trying to incorporate  player follows mouse position and fire via left click.
IE character follows mouse (player has own walkable area.)

At the moment it fires by spacebar which could still be used.

Can get the if mouse x / y do something etc its just getting player to follow.

Not quite sure where to find info as can't see in manual.

Could you help please?

Okay, so what you're saying is that you want the player to walk to wherever the mouse is at when they click the left mouse button?

...okay...

Code: ags

function on_mouse_click(MouseButton button)
{
  if (button == eMouseLeft) ProcessClick(mouse.x, mouse.y, mouse.Mode);
}

That's included in the default game template. And I'm pretty sure it's covered in the tutorial. And you didn't post any code, so if this isn't relevant then you need to tell us what you've actually done already instead of just saying what you want to do.

Looks like he means that he wants the player to walk non-stop to wherever the mouse is at (and fire by left mouse button click).

[steptoe]

Actually:

player walk to wherever mouse cursor is.

Fire with left click whenever.

cheers

EDIT: just seen this. Is this on the right track for firing (amend obviously)?

Code: ags

function on_mouse_click(MouseButton button) {
  if (button == eMouseLeft) {
  // Walk-to script
     ProcessClick(mouse.x,mouse.y,eModeWalkTo);
  }
  else if (button == eMouseRight) {
  // Activate script
     ProcessClick(mouse.x,mouse.y,eModeInteract);
  }
}

If what you mean is that the character should constantly walk towards the cursor, then no, that's not the code you want. You'll need something in the repeatedly_execute function. But you don't want to recalculate the walk path every cycle, so  you'll need some cleverer logic to only do the WalkTo if the cursor has moved significantly.

[monkey0506]

I wasn't sure if that's what he wanted.

If you want the player to follow the mouse around the screen I'd suggest doing this:

- Create a dummy character, name it cDummy.
- Create a view for cDummy, populate the loops with sprite 0, it doesn't need a graphic.
- Add the following to your repeatedly_execute function in GlobalScript.asc:

Code: ags

  cDummy.x = mouse.x;
  cDummy.y = mouse.y;

- Activate the following by:

Code: ags

player.FollowCharacter(cDummy, ...); // fill in dist and eagerness appropriately

I didn't test if FollowCharacter works if cDummy isn't actually Walking or Moveing (sic). If it doesn't you could set cDummy's movement speed very high and call cDummy.Walk/Move every loop.

I'll give that a whirl

How about if the room is the scrolling room? is that can conflict the game? I mean is that it will crash the game?

[monkey0506]

For a scrolling room just offset mouse.x and mouse.y by GetViewportX and GetViewportY.

Works brilliantly. However, after tweaking it about (distance,eager,speed etc) I find it not really suitable on this occasion as its difficult to do a slow pixel by pixel move as it were.

No doubt it will come in very useful in a situation where it needs be.

Cheers again

Steptoe, are you trying to make a kind of Space shooter game or something ?
If yes, forgot the character and use a cursor instead.

Otherwise, I'm still trying to figure what you're trying to do.

Well, in a round-about way, yes I suppose it is a shooter game.

The character moves side to side only and he shoots things with the spacebar.

You have to position yourself and line up the targets and fire.

A cursor (hair) would be inappropriate in this case as it would be too perfect, but I understand what you mean.

I suppose it's Arcade in style.

I didn't mean an hair, the character himself as a cursor, then lock the mouse edges using

Code: ags

 Mouse.SetBounds(int left, int top, int right, int bottom) 

Then with some code set the proper animation.

The other posibility is just to ask if the mouse.x is in left part of the screen (<160) or right part of the screen  (>160) then move the character straight to x0 or x320 (or whatever your room size) then use ismousedown in order to make him stopmoving() then proceed your shooting animation/test routine.

At least that's the way I'll do it.

[Khris]

Just to be clear about this:
To move a character, you don't have to use .Move or .FollowCharacter. You can directly set the coordinates.

I guess the underlying misunderstanding is the same as in the other thread and steptoe doesn't want the player to follow the mouse as in actually walk in its direction, he simply wants the character at the mouse position, instantly. He's just asking the wrong question because he doesn't have all the info.

This is for some arcade shooter game, right?

Try this in repeatedly_execute:

Code: ags

  player.x = mouse.x;
  player.y = mouse.y;

I could be completely wrong though so if I am, just ignore this.

Hi

nice code Khris but it does not conform to the game play as the player must only move to and fro across the walkable area.

Like at the rifle range at the fair: you can move side to side but never forward as it were.

Using 

Code: ags

player.x = mouse.x; 
player.y = mouse.y; 

will move the player anywhere the cursor is, similar to when the player has active inventory attached as you well know.

I'm quite happy as it is, not 100% perfik but durable until such time.

cheers all you guys



PS Maybe you can shed some more light on it if you play the game?

player.x = mouse.x; 
player.y = mouse.y; 

So just have it:

Code: ags

player.x = mouse.x; 

That way the player.y won't change, and the character will just slide along the screen from side to side.
