  • MarteEngine Tile Collision

    - by opiop65
    I need to add collision to my tile map using MarteEngine. MarteEngine is built of of slick2D. Here's my tile generation code: Code: public void render(GameContainer gc, StateBasedGame game, Graphics g) throws SlickException { for (int x = 0; x < 16; x++) { for (int y = 0; y < 16; y++) { map[x][y] = AIR; air.draw(x * GameWorld.tilesize, y * GameWorld.tilesize); } } for (int x = 0; x < 16; x++) { for (int y = 7; y < 8; y++) { map[x][y] = GRASS; grass.draw(x * tilesize, y * tilesize); } } for (int x = 0; x < 16; x++) { for (int y = 8; y < 10; y++) { map[x][y] = DIRT; dirt.draw(x * tilesize, y * tilesize); } } for (int x = 0; x < 16; x++) { for (int y = 10; y < 16; y++) { map[x][y] = STONE; stone.draw(x * tilesize, y * tilesize); } } super.render(gc, game, g); } And one of my tile classes (they're all the same, the image names are just different): Code: package MarteEngine; import org.newdawn.slick.Image; import org.newdawn.slick.SlickException; import it.randomtower.engine.entity.Entity; public class Grass extends Entity { public static Image grass = null; public Grass(float x, float y) throws SlickException { super(x, y); grass = new Image("res/grass.png"); setHitBox(0, 0, 50, 50); addType(SOLID); } } I tried to do it like this: Code: for (int x = 0; x < 16; x++) { for (int y = 7; y < 8; y++) { map[x][y] = GRASS; Grass.grass.draw(x * tilesize, y * tilesize); } } But it gave me a NullPointerException. No idea why, everything looks initialized right? I would be very grateful for some help!

  • Why do we need to put N before strings in Microsoft SQL Server?

    - by user61752
    I'm learning T-SQL. From the examples I've seen, to insert text in a varchar() cell, I can write just the string to insert, but for nvarchar() cells, every example prefix the strings with the letter N. I tried the following query on a table which has nvarchar() rows, and it works fine, so the prefix N is not required: insert into [TableName] values ('Hello', 'World') Why the strings are prefixed with N in every example I've seen? What are the pros or cons of using this prefix?
