How to use GetFriction?

Post by Ear1h »

I decided to make an inventory that gives tips after a player dies and I decided to make a condition if he stands on a certain sector with reduced friction
Spoiler:
The friction coefficient is specified in TERRAIN
Spoiler:
But he does not fulfil the condition, what should I do?

Without specifying a pointer, you are checking the friction of the sector the item is in, but the item doesn't follow the player once picked up.
If you want to specifically check the player's current friction, use the owner pointer for both GetFriction and A_Print:

Code: Select all

if(owner && owner.GetFriction() == 0.8)
{
owner.A_Print("Sand Soul slows you down!");
}
Also for debugging purposes you can use console.printf() to print the current variable to the console: console.printf(""..owner.GetFriction());

If you use ...GetFriction() == 0.8, the code does not work properly

However, using debug, I notice that the value in TERRAIN is significantly different from that displayed in the console. Instead of 0.8 the console shows 0.88751

I ended up using the inequality
