Forums » Help » Making an Enemy Walk Around a Platform

Hello:

I want to make an enemy walk all the way around the platform.
Like this:

!ig.game.collisionMap.getTile
to detect when he's near an edge on the X axis.

How can I detect when he's near an edge on the Y axis?

NM. I figured out how to use it.

I will post my solution for posterity:

     checkTiles: function(){
        //Tile Margins
        var tMX = 7;
        var tMY = 7;
        //Tile 1
        if (!ig.game.collisionMap.getTile(this.pos.x - tMX, this.pos.y - tMY)){
            this.cT1 = false;
        }
        else{
            this.cT1 = true;    
            console.log("CT 1 is True");
        }
        //Tile 2
        if (!ig.game.collisionMap.getTile(this.pos.x + this.size.x / 2, this.pos.y - tMY)){
            this.cT2 = false;
        }
        else{
            this.cT2 = true;    
            console.log("CT 2 is True");
        }
        //Tile 3
        if (!ig.game.collisionMap.getTile(this.pos.x + this.size.x + tMX, this.pos.y - tMY)){
            this.cT3 = false;
        }
        else{
            this.cT3 = true;    
            console.log("CT 3 is True");
        }
        //Tile 4
        if (!ig.game.collisionMap.getTile(this.pos.x - tMX, this.pos.y + this.size.y / 2)){
            this.cT4 = false;
        }
        else{
            this.cT4 = true;    
            console.log("CT 4 is True");
        }
        //Tile 5
        if (!ig.game.collisionMap.getTile(this.pos.x + this.size.x + tMX, this.pos.y + this.size.y / 2)){
            this.cT5 = false;
        }
        else{
            this.cT5 = true;    
            console.log("CT 5 is True");
        }
        //Tile 6
        if (!ig.game.collisionMap.getTile(this.pos.x - tMX, this.pos.y + this.size.y + tMY)){
            this.cT6 = false;
        }
        else{
            this.cT6 = true;    
            console.log("CT 6 is True");
        }
        //Tile 7
        if (!ig.game.collisionMap.getTile(this.pos.x + this.size.x / 2, this.pos.y + this.size.y + tMY)){
            this.cT7 = false;
        }
        else{
            this.cT7 = true;    
            console.log("CT 7 is True");
        }
        //Tile 8
        if (!ig.game.collisionMap.getTile(this.pos.x + this.size.x + tMX, this.pos.y + this.size.y + tMY)){
            this.cT8 = false;
        }
        else{
            this.cT8 = true;    
            console.log("CT 8 is True");
        }
        
    },

I am checking for collision tiles around the entity in 8 directions.
I am using this information to change the behavior of my entity.

Thanks for sharing your findings.
