But, think how much more challenging a simple game can be... Moo Ha Ha Ha... Let us try this dance again. Shall we? J Do you have any cheat code so that I can land it safely in the first attempt ? .... Oh, let me see... I think I stored it with my Chrystal Ball and my Wizard's wand... lol  Nah... I haven't even got the mechanics of the game sorted out yet... I am working on another version... Hopefully, if I can figure out how integrate Tilemap, then it should be a little easier to play. I have a hard copy of the Tilemap Editor document. It lists all the commands and provides an explanation, but there are no code samples... I am going to have to pick apart some of the N6 and N7 examples to try and figure out how to get it to work... Now, where did I put that Chrystal Ball?... Logic is the beginning of wisdom.

Maybe this is similar to what kevin did? kevin Member Posts: 52 Threads: 4 Joined: Dec 2023 Reputation: 4 04-01-2024, 03:30 PM (04-01-2024, 11:44 AM)Marcus Wrote: If you define the ground as a couple of connected lines, you can quite easily calculate the height at any x: Code:```set window "test", 640, 480 set redraw off ' Create an array of connected lines that cover the width of the window. lines = [] x0 = 0 y0 = 400 while x0 < 640     x1 = x1 + 16 + rnd(64); y1 = 400 + rnd(80) - 40     lines[sizeof(lines)] = [x0, y0, x1, y1]     x0 = x1; y0 = y1 wend ' Loop until excape is pressed. while not keydown(KEY_ESCAPE, true)     set color 0, 0, 0     cls         ' Draw the lines.     set color 255, 255, 255     for i = 0 to sizeof(lines) - 1         draw line lines[i][0], lines[i][1], lines[i][2], lines[i][3]     next         ' Mark the y coordinate of the ground at mouse x.     x = mousex()     y = GetY(lines, x)     set color 0, 255, 0     draw line x, y - 16, x, y         redraw     fwait 60 wend function GetY(lines, x)     y = 480     for i = 0 to sizeof(lines) - 1         if x >= lines[i][0] and x < lines[i][2]             k = (x - lines[i][0])/(lines[i][2] - lines[i][0])             y = lines[i][1] + k*(lines[i][3] - lines[i][1])             break         endif     next     return y endfunc``` I still haven't read through this thread yet, sorry. Maybe this is similar to what kevin did? Great example - I will be keeping this with other collision routines that I have.  It's similar to the one I posted - it is checking for the Y value for any given X value. The main difference is that I was demonstrating one way to check for collisions against a freehand landscape that has been drawn as a .png image file. I've used the routine in the past for a "defender" type game, and it seems to work well in that type of thing. 1micha.elok Member Posts: 159 Threads: 17 Joined: Nov 2023 Reputation: 0 04-02-2024, 08:50 AM (This post was last modified: 04-02-2024, 08:51 AM by 1micha.elok.)

I am really struggling with how and when to use the appropriate commands. The document that I have gives a summary of the Editor and a list of all the Library functions but there are no examples... A tutorial for the Editor would be a good idea.... In the meantime, I have used the "old school" method to create the level, using a text file of the "map" layout. Using a simple Axial Aligned Bounding Box function, for collision detection, I have managed to land the ship on the pad successfully and also managed to test the crashing as well... At the moment, the collision detection, is only working for the landing pad... Not much point if I can only land and crash on one tile... lol The game is still to short and a bit difficult to land... but it does land (and crash) on the red pad just fine... lol   lander3.zip (Size: 51.4 KB / Downloads: 4) I am slowly going nuts with this one... maybe a nice game of Pong?... *sigh* Logic is the beginning of wisdom.

Add some lunar storms to mess with the player and it'll be a hit! johnno56 Senior Member Posts: 252 Threads: 27 Joined: Nov 2023 Reputation: 3 04-02-2024, 06:13 PM I have already setup another 8 maps... But, the current method of game play, is not what I am aiming for... The orbiter idea came from a Scratch game I saw many moons (mo pun intended) ago... Originally, the Lander will start from the green pad, take off and land on the red pad, using a limited amount of fuel. (this will be added once everything is working... lol) As I had not quite figured out the collision issues, I figured that the Lander, would "drop" to the surface.... It's just gone 5am and I need to get the coffees made before my wife heads off to work... Logic is the beginning of wisdom. « Next Oldest | Next Newest »
