i have a small problem with this code:


As i understand my own code i load up an image substract the part i need from it and place it in image 1 and make a sprite off it and place it in sprite 1. If i press left mouse button it should turn 180 degree and if i press button two it should turn 90 degree. All good so far it works but it doesn't turn anymore if i press the button a second time.If i press left and then right and then left again it goes back to the place where it was after i pressed left for the first time while it shouldn't rotate to that position.

Any ideas on this i bet simple problem

The rotate sprite command is absolute and doesn't add together. Try rotating it by it's angle + 90 and it's angle + 180 like this:

thanks that solved the problem
a few other questions though:
°when i load the plane image and then draw some mountains on the screen, how do i determine wich one is on top, its 2d so when i move the plane where the mountain is i want the mountain to be displayed, is it so that the last one drawn in the loop will be on top (seems most logical to me)

°I noticed that when i use the rotate command it takes one of the courners to rotate it, how do i get it to rotate around the middle of the image?

°whats the best way to move the sprite using the mouse: making a sprite of the image in the loop or pasting it in the loop or an other way.

°Is there a way to include the images in the exe or do you have to copy the map over when you want to run it on an other pc.

°Is there a site that has all kinds of free 2d images to use in my test games, because my gfx skills are not very high.

°when i have a image to use as the background do i have to copy it manually to make it the background on the whole screen or is there a command that fills the whole screen with that image (eg: background image is 64*64 and resolution is 800*600 and i want to fill the whole background with that image)

I had some other questions too but i can't remember em now :s, so most likely i ll update this thread a few times so that i don't start too many threads.

Offset sprite [sprite number],[sprite width/2],[sprite height/2](i think)

paste sprite [sprite number],mousex(),mousey()

No.

set sprite priority is the command you need to specify what order sprites are drawn.

Boo!

Either use mod or %%

mod won't turn blue but is a valid command.


The word "Gullible" cannot be found in any English Dictionary.

hehe new question
how do i make the collision the way that it doesn't detect collision between the transparant pixels of my sprites
i thought the sprite hit command did that but it seems it doesn't :s
also when i just paste a sprite the sprite that is made with the sprite command is still there and the collision will occur whit the one i made with the sprite command and not with the pasted one

mms i also can't figure out how i spawn 1 enemy every three seconds i used this expression:
((timer()/1000)-starttime)%%3 =0
and then i run thru an array to see what sprite is available to spawn but it spawns all and not one

i can't seem to find a fault in my code

that would mean ((timer()/1000)-starttime)%%3 =0 is always true...

...after testing, ((timer()/1000)-starttime)%%3=0 for the whole of one second, you need to make it only go through the if once per second, not for every 0

yeah i thought it was something like it but i can't get it to do it once i thought of:
((timer())-starttime*1000)%%3000=0
but then it doesn't always do it i think because the loop can take longer than 1/1000 of a second right? So you got any sollution
Also my collision is still doing collision between transparant pixels (believe that is called bounding rectangle collision) and not impact collision, i need help on that one too.
