Forums » Help » Point and click - entities as buttons

Hello guys!

For some kind of point and click adventure game, I need to put an entity into the screen that changes its image when the mouse is over it (like a rollover) and also be able to be activated like a button to change the level...

I've been looking around in the posts for a while but i'm still not sure is the following is possible to do in Impact!, any help?
thanx so much!

update: function() {
			x = (ig.input.mouse.x + ig.game.screen.x);
			y = (ig.input.mouse.y + ig.game.screen.y);
			if(x >= this.pos.x && x <= this.pos.x + this.size.x && y >= this.pos.y && y <= this.pos.y + this.size.y){
				this.hover = false;
			}

I use something like this, and just have a check wherever you set your animations:

if(this.hover){
				this.currentAnim=this.anims.hover;
			} else {
				this.currentAnim = this.anims.idle;
			}

Ok, in that first codeblock it's obviously supposed to be "this.hover = true;", I'll just post the fixed version here:

update: function() {
            x = (ig.input.mouse.x + ig.game.screen.x);
            y = (ig.input.mouse.y + ig.game.screen.y);
            if(x >= this.pos.x && x <= this.pos.x + this.size.x && y >= this.pos.y && y <= this.pos.y + this.size.y){
                this.hover = true;
            } else {
				this.hover = false;
			}

Thank you so much Krisjet, i'll take a look at your code right now, wow, really nice!

Hi, I've been playing with the code above, and It seems to work with a fixed area in the screen, but i also need to do the same thing with entities moving around. So i wonder i there's some way to check if the mouse pointer is in collision against an entity on the screen...any clues?
tnx in advance!
