i probably need to start from scratch on this one. since i'm just working with hard-coded maps for now, i built a function to read the map and build an array of tile information (passable, block line of sight...) to be used in my movement checker. Maybe i should just read the map value and evaluate each tile from that? I'm planning to implement a bitset for this, but i'm not sure i need it. Anyway, i forgot to ever call this function after i made it, so i went and made a bunch of changes trying to fix it when it didnt work. I've tried to backtrack, but now it is acting very strange.
At first, it would not stop my character from moving at all, and the checkspace function was returning 0 all the time. So i changed the else condition of my array builder to be false, which should make all movement impossible. But it makes just a couple of seemingly random tiles and an entire row towards the middle of the map impassable. It does return values now, and i'm trying to use those to track down what i screwed up (maybe my formula on converting a 1D array to a 2D array?) I know i'm doing something very wrong, but am having trouble pin-pointing it. Any help would be very appreciated.
the map is a u16 array, the list array is of type "tile" currently defined in monster.h because that's where it 'works', i know i need to move it:
Here is the temporary flag array in main.cpp:
invoking the checkSpace method of the player object in main.cpp:
the checkSpace function in monster.cpp:
Let me know if you need more information. I'd also be willing to email a copy of my entire project folder or the .nds file upon request.
One thing i just noticed is that in struct tile "type" is defined as an int, but my map units are u16, but it doesn't seem like that should be causing the strange results i'm getting, should it? Gar, i wish i had internet access at my dev machine, this whole process would be so much easier...

| Code: |
| struct tile// does not belong in monster.h - how to move it but keep everything working?
{ // pointer to object or int ID, something to find what is on the tile for pickup item or fight monster... bool passable; // default not passable bool blockLOS; // default block line of sight int type; }; |
Here is the temporary flag array in main.cpp:
| Code: |
| void tempBuildList() // just until we get some actual level generation set up, then build list and map at same time
{ // use list as map? or map as list... int iz, iy, ix, i = 0; for(iz = 0; iz < 3; iz++) { for(iy = 0; iy < 64; iy++) { for(ix = 0; ix < 64; ix++) { i = ix + (iy * 64);// n = x + (y * w) list[iz][iy][ix].type = map2_64x64[i]; if (map2_64x64[i] == 4) { list[iz][iy][ix].passable = false; } else { // this should be true - trying false to see what happens. list[iz][iy][ix].passable = false; } } } } } |
invoking the checkSpace method of the player object in main.cpp:
| Code: |
| i = player->checkSpace(direction, list);
switch (i) { case (0): player->moveMonster(direction); //direction = D_NONE; break; case (1): // combat? //direction = D_NONE; break; case (2): // bump //direction = D_NONE; break; case (3): // swim? //direction = D_NONE; break; case (4): // open? //direction = D_NONE; break; default: // nothing there, go for it! player->moveMonster(direction); break; } |
the checkSpace function in monster.cpp:
| Code: |
| int Monster::checkSpace(int direction, tile plist[3][64][64])
{ // potentials int potX = 0; int potY = 0; // 0=none 1=Creature 2=Wall 3=Water 4=Door int obstacle = 0; /* 1) check creature array for monsters fight? 2) check terrain array for walls/water/door bump head/ swim? / open? */ switch (direction) { // first figure out what square we're looking at case (D_UP): potX = this->x; potY = this->y - 1; break; case (D_RIGHT): potX = this->x + 1; potY = this->y; break; case (D_DOWN): potX = this->x; potY = this->y + 1; break; case (D_LEFT): potX = this->x - 1; potY = this->y; break; default: potX = this->x; potY = this->y; break; } if (plist[0][potY][potX].passable) { obstacle = 0; } else { obstacle = plist[0][potY][potX].type; } return obstacle; } |
