问题 All I know is that delta relates somehow to adapting to different frame rates, but I'm not sure exactly what it stands for and how to use it in the math that calculates speeds and what not. Where is delta declared? initialized? How is it used? How are its values (min,max) set? 回答1: It's the number of milliseconds between frames. Rather than trying to build your game on a fixed number of milliseconds between frames, you want to alter your game to move/update/adjust each element/sprite/AI based

问题 Before asking this i did A LOT of searching on the net. I just can't do it. It's a little hard for me to understand. So how do i draw the images at the right screen positions coresponding to bodies in world position? Thanx. If anyone else finds himslef in front of the same obstacle i posted a HOW TO, thanx to normalocity's good explanation.

问题 I am trying to make a game in Slick, and before I start I want to test the helicopter animation I will be using. It just opens and then immediately closes with these errors: Exception in thread "main" java.lang.RuntimeException: There must be one duration per frame at org.newdawn.slick.Animation.(Animation.java:111) at javagame.Menu.init(Menu.java:22) at javagame.Game.initStatesList(Game.java:19) at org.newdawn.slick.state.StateBasedGame.init(StateBasedGame.java:170) at org.newdawn.slick

问题 I am trying to load and render levels (tile maps) in Slick2D from text files. The text files look something like this: res/RPGSheet 32x32.png (tileset to be used with this map) 5 (How many tiles wide the map is) 5 (How many tiles tall the map is) 16 (How many tiles wide the tileset is) 16 (How many tiles tall the tileset is) 4,1 4,1 4,1 4,1 4,1 4,1 1,1 2,0 4,1 4,1 4,1 4,1 1,1 4,1 4,1 4,1 1,1 4,1 1,1 4,1 4,1 4,1 4,1 4,1 4,1 First I'll explain how my tilemaps work: Each coordinate indicates

问题 So here is my problem: I'm a (new) java programmer and I need help for the game I am developing with Slick and LWJGL. What I want to do is really simple: make the player (or the image representing the player) head towards the mouse once I hold down the mouse button. I don't want it to rotate towards the player. Here's what my "Play" class looks like: package com.stuntmania.game; import org.lwjgl.input.Mouse; import org.newdawn.slick.Animation; import org.newdawn.slick.Color; import org

问题 I am trying to use the vertex buffers object. At first there wasn't any problem until I got into this nasty situation: glPointSize(2.0f); glBegin(GL_POINTS); for (Entity p : points) { glVertex3f(p.x, p.y, p.z); } glEnd(); How can I convert this into the Vertex Buffers Object render? I mean as you can see, the data (x, y, z) are changed every time for each point (it's a loop ). So how can i implement the Vertex Buffers Object render into this? 回答1: Basically what you want it putting all the

问题 I have made a 2D java game using Slick and it extends StateBasedGame, it does not extend JApplet so it is not really a real application but from the link bellow it shows that StateBasedGame is part of the Slick API and it can be used as an applet if the html code is coded correctly, here is the link: http://ninjacave.com/slickapplet I tried modifying it to fit my code and came up with the following: <applet code="org.lwjgl.util.applet.AppletLoader" archive="lwjgl_util_applet.jar" codebase="."
