02. Animate Propulsion
In this step, we will create a ship propulsion animation.
Start by modifying the ship we drew in the last step.
Tip: Press up to shift the ship up a pixel. This will give you the space you need to add the jetstream pixel without having to redraw the ship!
Now create a second ship where the jetstream pixels swap.
Enter this code on tab 0 in the code editor.
t=0
function _init()
cls()
ship={sp=1,x=60,y=60}
end
function _update()
t=t+1
if(t%6<3) then
ship.sp=1
else
ship.sp=2
end
end
function _draw()
cls()
spr(ship.sp,ship.x,ship.y)
end
Hit ctrl-r to run the game. A ship will appear with an animated jetstream!
