@Dave thats great man im going to rework this game iv got all my assets so not to much of a bugger,
honestly cant thank you enough iv got that structure for the other build just didnt think it would work the same for this whoo hoo!!!!!

Dave

@waldron Very glad to be of help dude! Give me a shout if you need anything :)

waldron

@Dave you'l regret saying that.. haha

i'm getting used to adding my enemies in game now but how can i change there death state from
collision/velocity (jumping into them) to a button attack (c.x) from my player?
if i can master that i can then add animation to my level and crushing blocks and spikes coming out of walls ect but give them a state where they kill me

Dave

I think you could use multiple death states, each having their own specific spritesheet to draw from, and requisite conditions to trigger them. Something like:

(Of course, this is pseudo-code)

if collide with enemy and playerState != attack then
    enemyState = death1
endif
if collide with enemy and playerState == attack then
    enemyState = death2
endif
if enemyPosition overlaps with kill box then
    enemyState = death3
endif

There is probably a much more lovely way of doing this, but this is the route I would personally go down.

Then, you'll have specific conditions for each of those death states:

if enemyState == death1 and collides with player then
     // do specific things    
endif

@Dave wonderful stuff cheers

waldron

I very nearly gave up, with all these ideas floating around my head trying to implement them all just caused confusion.

So I stripped it back down to what I think I know and fixed all the confusion to something I can build on.

With huge magnitudes of greatfullness for the fuze team and users.Thankyou!!!

@waldron Awesome work man! This is really coming along!

waldron

any idea how i can fix my points for tricks, at the moment iv assigned score to a button press (trick) but obviously the user can just sit there and rack up a huge score.

I thought i cracked it last night by putting in movement speed for the opposite direction while pressing the button which actually gave it a great effect of grinding to a halt but then starts moving in the other direction and breaks the effect.
so is there a way i can create a dead zone so i can keep this set-up but have the movement and score to stop once my character is not moving ? i can provide a video later to help explain

actually just figured out the movement thing by changing the direction of movement to y. axis.down so now i just need
the score fixing

@waldron I don't know if I'm following completely, but one thing I've been doing when I need a "cool down" is to have a global integer, then in my gameplay code I subtract it by one, and say "is it zero yet? if so, let them do action XYZ again".

waldron

@Spacemario i'l upload a video later altho a cool down does sound like a possible fix just don't know how i would code it,
my code from memory atm is kinda like

if c.y state = trick then
playerY movespeed -= // gives me the drag effect (slowdown)
playercoin += 1            // gives me the score 
.........so on so on

level is getting rather large now think im at 350 columns in length, really want to start introducing moving platforms i thought i could use the data from my enemy's and modify it but still proving to be a problem with my ability to code.and help would be greatly appreciated

Martin

I would have thought moving platforms would pretty much be enemies too. But instead of dying when you collide with the top of the sprite you just land on it. Maybe a little more complicated in that you need to detect just the top of the sprite(s), not the bottom or sides but beyond that I don't see a lot of difference.

waldron

@Martin il keep tinkering with the code, i got rid of the gravity so i have it floating and moving as of now
using this

     if enemies[i].state != death then
        enemies[i].velocity += gravity
        if !collision( x + eSize.x / 2, y + eSize.y + enemies[i].velocity / eSize.y ) then
            enemies[i].y += enemies[i].velocity / tSize
        else
            enemies[i].y = int( ( enemies[i].y + enemies[i].velocity / tSize + eSize.y / tSize ) ) - eSize.y / tSize
            enemies[i].velocity = 0
        endif
        if playerX + pSize.x > x and playerX < x + eSize.x and
            playerY + pSize.y > y and playerY < y + eSize.y and
            enemies[i].state == active and velocity > 0
        then
            enemies[i].state = death
        endif
    endif

wanting to rebuild my game using the level editor but having problems with the sprite camera following the player

Martin

Does centreSpriteCamera(player.x, player.y) not cut it ?

waldron

@Martin il test later that should do it, for another game im working on how would i manage the camera scrolling screen by screen

Martin

if it's a constant rate or similar then just track the X/Y co-ordinates, updating them frame by frame and then supply them just the same? I might need to better understand what you want to do...

waldron

@Martin the screen by screen, is for my prince of persia remake just dont know how to track the player character on the level editor with the camera been busy doing the sprite sheet stuff but will be loading into a test map soon and il share about quarter the way through with the sprite sheet :)
