Lately ive been using this code since I havent had a floor Code: //Handle the players gravity if( y + PLAYER_HEIGHT > SCREEN_HEIGHT - PLAYER_HEIGHT ) //If the player is on the ground { //only if falling is true (landing on the ground) if( falling == true && ( in_air == false && on_ground == false) ) { y -= yVel; yVel = 0; on_ground = true; falling = false; } } else //If you are not on the ground { if( on_ground == false ) { if( in_air == false ) { falling = true; } } } and Code: //When landing on the ground, make sure you are right above the surface if( on_ground == true ) { y=SCREEN_HEIGHT - (PLAYER_HEIGHT+16); } but then I created tiles, here is level.h Code: #ifndef LEVEL_H_INCLUDED__ #define LEVEL_H_INCLUDED__ class Tile { private: //The dimmensions int tile_dimx; int tile_dimy; //The offset int x; int y; public: Tile(); void show(int x, int y); }; #endif // LEVEL_H_INCLUDED__ and level.cpp Code: #include "constants.h" #include "globals.h" #include "level.h" #include <iostream> #include <cstdlib> Tile::Tile() { tile_dimx = tile_dimy = 16; //saves lines, since the dimmensions will be the same on both sides //x = 0; y = SCREEN_HEIGHT - tile_dimy; } void Tile::show(int x ,int y) { //Show the animation apply_surface( x, y, tiles, screen, &screen->clip_rect); } In main.cpp, I have Code: Tile tiles; and they are spawned as so Code: tiles.show(0,SCREEN_HEIGHT-16); for example, 0 being x and SCREEN_HEIGHT-16 being y. Now, how can I change the code around so that the player checks if it is on top of the tile? That is all the collision code there is to my program. Also, I would like to know if I can do arrays and structs like I can in Bennu. By that, I mean can I load a file that has the x and y coordinates saved for that specific array, and and the the tiles are placed by the array coutning up or whatever? here is some bennu code: Code: // put the blocks FOR (tile_count_x=0; tile_count_x<TILE_DIMX; tile_count_x+=1) FOR (tile_count_y=0; tile_count_y<TILE_DIMY; tile_count_y+=1) IF (level.tile[tile_count_x][tile_count_y].used==TRUE) // make sure that the tiles are put on the right place temp_x=(tile_count_x*block_size)+8; temp_y=(tile_count_y*block_size)+8; block_graph=level.tile[tile_count_x][tile_count_y].kind; //map_xputnp ( <INT destinationFileID> , <INT destinationGraphID> , <INT originFileID> , <INT originGraphID> , <INT x> , <INT y> , <INT angle> , <INT scale_x> , <INT scale_y> , <INT blitflags> ) // put a block into the scroll map_xputnp(0,scroll_map,block_fpg,block_graph,temp_x,temp_y,0,100,100,0); say("plotting tile: "+tile_count_x+" , "+tile_count_y); END END END thanks! ____________ |
