  • non randomic enemy movement implementation

    - by user601836
    I would like to implement enemy movement on a X-Y grid. Would it be a good idea to have a predefined table with an initial X-Y position and a predefined "surveillance path"? Each enemy will follow its path until it detects a player, at this point it will start chasing it using a chasing algorithm. According to a friend of mine this implementation is good because the design of a good path will provide to the user a sort of reality sensation.

  • Separating logic and data in browser game

    - by Tesserex
    I've been thinking this over for days and I'm still not sure what to do. I'm trying to refactor a combat system in PHP (...sorry.) Here's what exists so far: There are two (so far) types of entities that can participate in combat. Let's just call them players and NPCs. Their data is already written pretty well. When involved in combat, these entities are wrapped with another object in the DB called a Combatant, which gives them information about the particular fight. They can be involved in multiple combats at once. I'm trying to write the logic engine for combat by having combatants injected into it. I want to be able to mock everything for testing. In order to separate logic and data, I want to have two interfaces / base classes, one being ICombatantData and the other ICombatantLogic. The two implementers of data will be one for the real objects stored in the database, and the other for my mock objects. I'm now running into uncertainties with designing the logic side of things. I can have one implementer for each of players and NPCs, but then I have an issue. A combatant needs to be able to return the entity that it wraps. Should this getter method be part of logic or data? I feel strongly that it should be in data, because the logic part is used for executing combat, and won't be available if someone is just looking up information about an upcoming fight. But the data classes only separate mock from DB, not player from NPC. If I try having two child classes of the DB data implementer, one for each entity type, then how do I architect that while keeping my mocks in the loop? Do I need some third interface like IEntityProvider that I inject into the data classes? Also with some of the ideas I've been considering, I feel like I'll have to put checks in place to make sure you don't mismatch things, like making the logic for an NPC accidentally wrap the data for a player. Does that make any sense? Is that a situation that would even be possible if the architecture is correct, or would the right design prohibit that completely so I don't need to check for it? If someone could help me just layout a class diagram or something for this it would help me a lot. Thanks. edit Also useful to note, the mock data class doesn't really need the Entity, since I'll just be specifying all the parameters like combat stats directly instead. So maybe that will affect the correct design.

  • Of what significance is the solution to the game of checkers in AI research?

    - by cobie
    I have been doing some research into artificial intelligence and I came across a 2007 paper titled "Checkers is Solved" on the game of checkers being solved by AI techniques after more than 16 years of trial. A solution to the game is defined by the team as "determining the final result in a game with no mistakes made by either player". The search for a solution started back in 1989 and it was finally found in 2007. Of what importance is this to the field of AI?

  • Platformer Collision Error [closed]

    - by Connor
    I am currently working on a relatively simple platform game that has an odd bug.You start the game by falling onto the ground (you spawn a few blocks above the ground), but when you land your feet get stuck INSIDE the world and you can't move until you jump. Here's what I mean: The player's feet are a few pixels below the ground level. However, this problem only occurs in 3 places throughout the map and only in those 3 select places. I'm assuming that the problem lies within my collision detection code but I'm not entirely sure, as I don't get an error when it happens. public boolean isCollidingWithBlock(Point pt1, Point pt2) { //Checks x for(int x = (int) (this.x / Tile.tileSize); x < (int) (this.x / Tile.tileSize + 4); x++) { //Checks y for(int y = (int) (this.y / Tile.tileSize); y < (int) (this.y / Tile.tileSize + 4); y++) { if(x >= 0 && y >= 0 && x < Component.dungeon.block.length && y < Component.dungeon.block[0].length) { //If the block is not air if(Component.dungeon.block[x][y].id != Tile.air) { //If the player is in contact with point one or two on the block if(Component.dungeon.block[x][y].contains(pt1) || Component.dungeon.block[x][y].contains(pt2)) { //Checks for specific blocks if(Component.dungeon.block[x][y].id == Tile.portalBlock) { Component.isLevelDone = true; } if(Component.dungeon.block[x][y].id == Tile.spike) { Health.health -= 1; Component.isJumping = true; if(Health.health == 0) { Component.isDead = true; } } return true; } } } } } return false; } What I'm asking is how I would fix the problem. I've looked over my code for quite a while and I'm not sure what's wrong with it. Also, if there's a more efficient way to do my collision checking then please let me know! I hope that is enough information, if it's not just tell me what you need and I'll be sure to add it. Thank you! [EDIT] Jump code: if(!isJumping && !isCollidingWithBlock(new Point((int) x + 2, (int) (y + height)), new Point((int) (x + width + 2), (int) (y + height)))) { y += fallSpeed; //sY is the screen's Y. The game is a side-scroller Component.sY += fallSpeed; } else { if(Component.isJumping) { isJumping = true; } } if(isJumping) { if(!isCollidingWithBlock(new Point((int) x + 2, (int) y), new Point((int) (x + width + 2), (int) y))) { if(jumpCount >= jumpHeight) { isJumping = false; jumpCount = 0; } else { y -= jumpSpeed; Component.sY -= jumpSpeed; jumpCount += 1; } } else { isJumping = false; jumpCount = 0; } }

  • Client-side prediction for FPS

    - by newprogrammer
    People that understand client-side prediction and client-side interpolation, I have a question: When I play the game Team Fortress 2, and type cl_predict 1 into the developer's console, it enables client-side prediction. The also says "6 predictable entities reinitialized". It says this regardless of how many players are on the server, which makes sense, because other players are not predictable entities. I thought client-side prediction was only for the movement of the player. Are there other entities that the client can provide prediction for?

  • How do I save files with libgdx so that users can't read them?

    - by Rudy_TM
    Writing my game in libgdx, I arrived at the point when I need to save the player stats and the info of the levels. However, in libgdx it's not allowed to write the file inside folder of the application, only external (on the SD) is allowed. The point is that I don't want the file to be seen by anyone, or if they can see it, how can I convert it to a binary file so it's not human readable? I just want to hide the file.

  • SEO Link Building - An Important Part of Online Marketing

    You must remember that SEO link building is something that is a very important part of online marketing. The latter is a field that has in recent times become a real money churner for corporate conglomerates. SEO link building is so important that now you have marketing companies that specialize in this particular field alone. It should be noted that such online marketing per se will not help you garner great sales; you should also be highly involved in social media as well.

  • How do I deal with the problems of a fast side-scroller?

    - by Ska
    I'm making a side scrolling airplane game and when I begin going very fast I begin to experience some problems as a player: Elements are not distinguishable, like power-ups from bullets, etc I start to feel dizzy and uncomfortable There isn't enough time to see what's coming How can I sort this out? Do I use less details in all the grahpics? Tiny Wings has the same horizontal movement speed as in my game but it doesn't suffer from these problems. Are there any other really fast side-scrollers I could take as a reference?
