You can use a different easing just passing some
ease_* script to
the "ease" VAR when you are creating your tween. For example, to use the
ease_bouncein ease in your tween:
tween_to(id, 1, array("x", x + 200, "ease", ease_bouncein));
Tweenline currently supports 35 different easing types.
You can use modifiers on some eases to change their behaviour.
For example, you can change the
overshot on the
to to create a more dramatic effect.
All the modifiers are real values. If you pass a non real
argument, the default value is used instaed.
ease_back (in/out/inout) modifiers
overshot: [default = 1.70158]
Overshoot affects the degree or strength of the overshoot.
ease_pow (in/out/inout) modifiers
power: [default = 6]
Adjust which power() function will be used to calculate the tween. As big is the power modifier, more pronunced will be the easing. Try to use a small number, as this function has a big CPU overhead. If you want to use a number below 6, please use: (they are super optimized)
power = 1, use
power = 2, use
power = 3, use
power = 4, use
power = 5, use
tween_set_modifiers(tween_index, [linearRatio, power, yoyoMode]);
linearRatio: [default = 0.7]
The proportion of the ease during which the rate of change will be linear (steady pace). This should be a number between 0 and 1. For example, 0.5 would be half, so the first 25% of the ease would be easing out (decelerating), then 50% would be linear, then the final 25% would be easing in (accelerating). If you choose 0.8, that would mean 80% of the ease would be linear, leaving 10% on each end to ease.
power: [default = 0.7]
The strength of the ease at each end. If you define a value above 1, it will actually reverse the linear portion in the middle which can create interesting effects.
yoyoMode [default = false]
If true, the ease will reach its destination value mid-tween and maintain it during the entire linear mode and then go back to the original value at the end (like a yoyo of sorts). This can be very useful if, for example, you want the alpha (or some other property) of some text to fade at the front end of a SlowMo positional ease and then back down again at the end of that positional SlowMo tween. Otherwise you would need to create separate tweens for the beginning and ending fades that match up with that positional tween.
